In this study, we propose functionally graded material (FGM) type electromagnetic wave absorbers for a hollow cylinder and investigate an electromagnetic noise problem and a plane-strain thermoelastic problem of those absorbers. The absorption layer with graded composition is considered as a multilayered absorption layer. We present the analytical solutions of electromagnetic and temperature fields in the FGM type cylindrical absorbers subjected to the irradiation power. The thermal stress distributions are also analyzed based on the stress function method. Numerical calculations for absorption performances and thermal stresses are carried out for the FGM type cylindrical absorbers with absorption layers composed of epoxy resin matrix and conductive titanium oxide particles.
