ASERIS-BE^TM is based on the solution of Boundary Integral Equations (BIE) derived from Maxwell’s equations in the frequency domain, offering very accurate numerical approximation.

It requires reduced modelling effort, smaller model sizes and lower memory consumption, as it is based only on the meshing of the interfaces between different homogeneous domains. Electric and magnetic fields are deduced effectively in the observation domain, using the integral representation formulas in the post-processing stage. With this approach, when additional result points are needed, there is no need to re-mesh and re-solve the initial model, offering flexibility and reduced computational time.

The solver handles perfect or imperfect conductors, dielectric materials, resistive or composite sheets, electric wires, ground planes and geometrical symmetries, lumped voltage sources and impedances, waveguides, incident plane waves, point sources etc. Furthermore, it offers the possibility of replacing radiation sources with equivalent Huygens surfaces that are unidirectionally coupled to their surroundings. It is worth noting that the solver features low-frequency stabilization, which allows it to address broadband problems from very low to very high frequencies.

ASERIS-BE^TM computational technology can find its application in problems for:
 - Antenna applications: Optimization and design, Antenna placement, Management of Radio-Frequency Compatibility (RFC) on platforms, Wireless communication systems, Instrument Landing System (ILS) and airport environment, Beamforming…
 - Electromagnetic Compatibility (EMC): Radiated emissions, Immunity testing, Electromagnetic Interference (EMI) and cross-talk…
 - Radar applications: Radar Cross Section of targets in aerospace, marine and automotive, Design and optimization of Radar Systems, RF sensors (e.g. in autonomous driving, remote sensing, non-destructive testing, etc.)
 - Lightning protection of buildings, aircrafts etc.
The implementation of the software may be further extended to other areas, such as Electronics: Signal integrity, Power integrity, S-parameters of interconnects etc.

By combining the implementation of fast computational methods (FMM, H-Matrix) with a pure surface mesh formulation, the solver demonstrates very high performance. Being coupled with the efficient pre- and post-processing software of BETA, the overall solution demonstrates high quality and reduced overall processing time.
