Modeling and Optimization of Advanced Multilayered Absorbers

Abstract—In this contribution we present a design environment
for the optimization of layered absorbers. The manufacturer
has a wide set of materials with known properties available.
The thickness of these materials can vary within given limits. For
a given number of layers and given absorption requirements as
a function of angle of incidence, polarization and frequency we
try to optimize for the thicknesses of the layers and for the
best possible choice of available material types. The optimization
for the layer thicknesses is done using a simulated annealing
technique and for selecting materials usually the whole discrete
design space is sampled. The paper is illustrated with two
realizations comprising comparisons between simulations and
measurements.
