Abstract: This paper presents a solution to an inhomogeneous problem of
electromagnetic wave propagation through a functionally graded wave-absorbing
(FGWA) infinite thin plate. The FGWA plate compounded by dielectric and
magnetic materials has an arbitrary inhomogeneity through its thickness. The
characteristics of the electromagnetic wave absorption and the temperature
field due to the heat energy arising from electromagnetic wave absorption in
the plate are analyzed. The results demonstrate that the electromagnetic wave
absorption properties have been significantly improved for the gradient
absorbing plate in comparison with the homogeneous one. With the proper
gradient distribution design of material properties, the FGWA plate shows good
performance on the lower reflection and high absorption.
Keywords: Functionally graded wave-absorbing plate, absorption and reflection, power dissipation, thermal properties
