abstract = {<p style="text-align: justify;">The electromagnetic backscattering of a crosscut of a cruise missile coated
by a thin homogeneous layer made of radar absorbent material is modeled using a
finite element method. Based on the radar cross section and a reflection coefficient,
optimization problems are formulated for evaders and interrogators leading to optimal
material parameters for the coating and optimal monostatic radar operating frequencies,
respectively. Optimal coating materials are constructed for several radar frequencies.
Tuning only dielectric permittivity gives a narrow frequency range of high absorption
while also tuning magnetic permeability widens it significantly. However the coating
layers considered do not provide substantial reduction of backscattering in the entire
frequency range from 0.2 to 1.6 GHz. Computational experiments also demonstrate
that the reflection coefficient based on a simple planar geometry can predict well the
strength of radar cross section in the sector of interest with a substantially reduced
computational burden.</p>},
