A Circuit-based Model for the Interpretation of Perfect Metamaterial Absorbers
Filippo Costa, Simone Genovesi, Agostino Monorchio +1
A popular absorbing structure, often referred to as Perfect Metamaterial Absorber, comprising metallic periodic pattern over a thin low-loss grounded substrate is studied by resort…
Analysis and Design of Ultra Thin Electromagnetic Absorbers Comprising Resistively Loaded High Impedance Surfaces
Filippo Costa, Agostino Monorchio, Giuliano Manara
High-Impedance Surfaces (HIS) comprising lossy Frequency Selective Surfaces (FSS) are employed to design thin electromagnetic absorbers. The structure, despite its typical resonant…
An Active High Impedance Surface for Low Profile Tunable and Steerable Antennas
Filippo Costa, Agostino Monorchio, Salvatore Talarico +1
In this letter, an approach for designing a tunable and steerable antenna is presented. The antenna model is based on a wideband bow-tie radiating element mounted above an active A…
A Thin Electromagnetic Absorber for Wide Incidence Angles and Both Polarizations
Olli Luukkonen, Filippo Costa, Agostino Monorchio +1
In this paper a planar electromagnetic absorber is introduced whose performance is maintained over a wide change of the incidence angle for both TE and TM polarization. The absorbe…
