Parametrized Absorber Model

Christoph Maeurer_20651

Overview

• Parametrized absorber model to compute the reflection coefficient for a plane wave

• Model with dielectric absorber and PEC plane behind the absorber

• Models for FEM and SEP available

• Efficient approach with periodic boundary conditions (PBC)

• Fully parametrized model allows easy optimization or sensitivity analysis using OPTFEKO or HyperStudy

• Version: CADFEKO2022.0

Pre-Requisite

Model can be loaded and simulated in CADFEKO 2022.0

More details about the model an design variables in the attached pdf-document

Usage/Installation Instructions

Tipps & Tricks:

• In Feko different options to model dielectrics are available. In this case FEM (Finite Element Method) is faster than SEP (Surface Equivalence Principle).

• Notice, that the FEM model contains an FEM airbox around the dielectric absorber. This trick is reducing the runtime significantly! 

• The method can be defined in the solution tab of the region properties.

• In this example the incident direction of the plane wave is perpendicular to the absorber wall, but arbitrary incident directions could be defined for the plane wave.
