TaraNG: 19.1  
The Interactive Learning Pedagogy!  
Our vision is to make science education more advanced & interactive. We are using integrated solution of AI  
and Simulation techniques to create unique hands-on based learning experience and to create a perfect class-  
room solution.  
It is collaborative efforts from institute i.e. the simulation models provided will be as per syllabus of particular  
subject, so teachers will get exactly what they need. It will also reduce paperwork which engineering students  
have to do during academic assessments, rather students can focus more on learning concepts as report  
generation and simulation on-go is at same place.

This module of Circuit schematic design allows user to design and simulate circuits with target high frequency  
simulation components. Both active and passive electronics systems. Active systems can have circuits such as Low  
Noise Amplifier (LNA), oscillators and mixers can be solved with correct explanation of gain and noise figure. In  
passive components user can design and solve Filters, power dividers, couplers, splitter etc. In mixed signal analysis  
module, the systems which may have both digital and analog components can also be simulated together, while  
taking care of microscopic delays.  
This module is featured with quick to use transmission line and PCB sections such as Microstrip line, Bend, Tee

TaraNG: 19.1  
An overview: Applications  
Antenna Design  
This module makes use of special numerical integration techniques that give the fastest results of any  
available electromagnetic software without sacrificing accuracy. With it, one can analyze various antennas,  
such as simple monopoles and dipoles, loops, broadcast tower antennas, log-periodic and Yagi-Uda, and  
much more.  
Dipole Antennas: infinitesimal dipole, half wavelength  
dipole, folded dipole and monopole antennas. These  
resonant antennas have small bandwidth hence referred  
as Narrow Band Antennas.  
Loop Antennas: Loop antennas replace dipole  
antennas where receiver is held closer to body  
and used in sensing and medical applications like  
peacemaker, MRI etc. Loop antennas take many  
different forms such as rectangular, circular,  
triangular and elliptical are among many.  
Broad Band Antennas: An antenna with wide bandwidth is referred as ‘Broadband antenna’ Rather than standing  
waves these antennas have travelling waves on them hence also referred as ‘Travelling Wave Antennas’.  
Conventional broadband antennas include bi-conical antenna, spiral antenna and log periodic antenna.  
Loaded Antennas: To prevent reflections from dipole or monopole end loading is used. Both distributed and  
lumped loading can be achieved. Antennas can be loaded with parasitic elements such as yagi-uda antennas.  
TaraNG: 19.1  
An overview: Applications  
Ultrawide Band Antennas: Ultra-wide band antenna (UWB) have small phase  
variation of transmitted signal over bandwidth hence UWB antennas are being used  
increasingly for high-speed RF wireless communication, high power RF jamming and  
high-resolution impulse radar systems for Ground Penetrating Radar (GPR). Example  
of UWB antennas includes bowtie, conical and vee shaped antennas.  
Multi-Band Antennas: A multiband antenna is an antenna designed to operate in  
multiple bands of frequencies. The structure of antenna can be repetitive in nature  
for example fractal antenna.  
Antenna Arrays & Antenna Coupling  
Antenna arrays can be designed to control their radiation characteristic by properly  
selecting phase/amplitude distribution and spacing between the elements.  
Linear and Circular Array: Linear and circular arrays of arbitrary elements with  
arbitrary spacing.  
Broadside / End-fire array: Broadside arrays generates their maximum radiation  
perpendicular to array axis. On the contrary an end-fire array directs its main lobe  
along the array axis.  
VLSI Interconnect & IC Packaging  
As the density, complexity, and speed of VLSI circuits are continuing to increase, the management of on-chip  
interconnects becomes of major concern to the I.C. designer. When group of conducting bars are kept together  
then filed coupling occurs which may result in induced field on nearby bar. The effects like proximity effect, Skeen  
effect need to be accurately modelled while designing VLSI interconnects or IC packaging. This module allows to  
extract these parasitic effects and tells behaviors.  
Although circuit performance can always be evaluated by a circuit solver like SPICE, this is usually very slow and fails  
to reveal relationship between interconnect structure and interconnect delays. This module allows on‐chip  
interconnect wires to be considered in circuit analysis for high precision analysis  
The goal of this module is to include interconnect parasitic in a circuit simulation as efficiently as possible, without  
significantly compromising accuracy  
TaraNG: 19.1  
An overview: Applications  
Microstrip Line Network Design (PCB)  
At higher frequencies electronic components shows non-ideal behavior, this change in behavior results of parasitic,  
leakages and coupling. However, these effects are predictable and can be taken positively. The area which deals  
with this kind of circuit design is microwave circuit design, in which circuit components are realized by choosing  
proper dimensions of path and hence no extra components need to be soldered on circuit boards.  
Microstrip lines are dual sided PCBs on one side these microwave circuits are realized and are easy to fabricate. RF  
& Microwave network design concepts are useful to realize filters, power dividers, couplers, resonators, stub or  
matching networks etc. at higher frequencies.  
2D Solvers  
Electrostatic Solver: Electrostatic analysis can be helpful for applications such as high voltage design and  
capacitance evaluation of capacitive systems such as fuses, cables & cable bundles, transmission lines and so forth.  
Generally, quantities of interest in electrostatic analysis are voltage, electric field, capacitances and electric forces.  
Magnetostatic Solver: Magnetostatic is the magnetic analogue to electrostatic where instead of charges currents  
are stationary. Applications of magnetostatic is to design motors and to extract inductance  
The quantities of interest in magnetostatic analysis are current, magnetic field, inductance and magnetic forces.  
This module is helpful in understanding field distribution across cross section of electromagnetic system. By  
idealizing one dimension of 3D system, rotational symmetry and axis symmetry can be solved using these 2D solver.  
TaraNG: 19.1  
An overview: Applications  
RADAR Cross Section Analysis  
When the size of scatterer (target) is larger i.e. larger than ten to thousand times wavelength. At this higher  
frequency full wave techniques are not suitable as it requires more computational power. TaraNG’s RCS Analysis  
module makes use of asymptotic methods to solve such large body problems without requiring computing  
resources viz. simulation time and memory yet producing accurate results.  
This module is capable of solving Bistatic and Monostatic RADAR cross section of target. The available import option  
allows user to import complicated CAD model file within the software and use it for further processing.  
Materials & coating: Perfect Electric Conductor (PEC), Impedance Boundary Condition (IBC), Resistive Sheet,  
Dielectric Sheet, Composite Layer, Multilayers composite with surface roughness.  
Basic Field Solvers  
3D Charge & Moment Solver: This module can solve electric field caused due to  
point charges kept in 3D space and magnetic field due to magnetic moments.  
Also, both electric & magnetic field can be solved due to dipole moments full  
wave method i.e. without making static approximation of green’s function and  
considering higher order exponential terms.  
Types of field plots: Quiver plot (oriented arrows), streamlines (field lines),  
Contour plot (Equipotential surfaces), Cut planes (field on given 2D plane) and  
radiation pattern formed due to dipole moments.
