## Electromagnetic solvers/simulators

Most of the time currently for electromagnetic simulations
and analysis we are using
[FEKO](https://altairhyperworks.com/product/FEKO)
and
[CST](https://www.3ds.com/products-services/simulia/products/cst-studio-suite/) commercial software for solutions of our
research and educational problems :

CST Studio Suite(R) is a high-performance
3D EM analysis software package for designing, analyzing, and optimizing
electromagnetic (EM) components and systems. We have commercial licenses
of all electromagnetic field solvers for applications across the EM
spectrum.

Our common subjects of EM analysis include the
performance-based design of antennas, transmission lines and filters,
the modeling of complex objects' radar cross-sections (RCS) and
polarization scattering matrices, the modeling of realistic communication
channels, and, also, the thermal analysis in high-power devices.

Numerical simulations form the first step of the design
process of the electromagnetic components. The simulation results and
final implementation of suitable designs can be validated in the
[DUCAT
anechoic chamber](http://radar.tudelft.nl/Facilities/ducat.php) and Microwave laboratory.

There are some examples of our realized designs:

Fig. 1. SIW based active cosecant phased antenna array for
future 5G systems

Fig. 2. Dual-Band wide-angle scanning planar phased array in
X/Ku-Bands

Fig. 3. L/S-Band frequency
reconfigurable phased array antenna

With these software packages, it is possible not only
to make the electromagnetic field simulations for the antenna systems and
array design but to solve much more computationally complex problems like
the electromagnetic wave propagation in real communication channels and
the signals scattering on complex objects. There is also a possibility
to combine the electromagnetic and thermal analysis that is very important
for the design of modern 5G antenna array with incorporated transmitting
distributed modules. A few illustrative examples of such communication
channel modeling and thermal design analysis are presented below.
