Abstract. Paper deals with the ability to transmit electromagnetic energy through the thick
dielectric screens (screen thickness is several skin depths) of
materials with high attenuation at microwave frequencies. The cases where the
screen is made of ordinary dielectrics
with low loss-angle tangent, with
metal-like materials with loss-angle close
to 900, and of plasma-like materials with loss-angle over
900 are considered. The case of absolute translucence
of lossless plasma-like material
is separately discussed. The results of studies
presented in this paper were
reported at the 6th All-Russian
Conference "Radar and radiocommunication."
