Design of thin wave absorbers using closely placed divided conductive film and resistive film

In this paper, design of thin wave absorbers using an admittance-sheet composed of closely placed resistive film and divided conductive film is studied. The admittance of the sheet has frequency dependence because of the mutual influence between the films. The matching frequency of the absorber depends on its thickness (&#60; λ/4) and susceptance of the sheet. Likewise the reflection value at the frequency depends on conductance of the sheet. Then, the design charts of the absorbers to perfect match at target frequencies are illustrated, and demonstrated the practicality by simulation of the reflection characteristics of the absorbers which designed based on it.
