Analysis and design of thin absorbers based on artificial magnetic conductors with resistive elements

In the article of Goussetis and Feresidis (2007), an improved thin absorber was proposed whereby improvement is achieved by virtue of the stronger currents excited by a normally incident plane wave on a dipolebased AMC with perturbed unit cell. A study of the currents was carried out both for the case of free-standing FSS and for array elements placed in the proximity of a ground plane. In this contribution as an extension of that work, a parametric study is carried out to present design guidelines and demonstrate optimized performance. The study is based on an in-house MoM code and simulations by a commercial software (Ansoft Designer) are also presented for validation of the performance.
