Abstract :
The treatment of a thin absorber as a boundary condition, taking the arbitrary thickness of the absorber into account, is presented. To verify this approach, the equivalent circuit is applied to the terminal model of a coaxial line and rectangular waveguides. Its validity is verified by changing the medium constant, frequency, and angle and polarization of the obliquely incident wave. To illustrate the application of the approach to a complicated structure, the reflecting and scattering characteristics of an aircraft model are presented
