A procedure for the optimal design of compact and light-weight electromagnetic absorbers is presented. The absorbers are designed to damp resonances inside metallic enclosures on the basis of Jaumann's theory; several layers of lossy (artificial) dielectrics are separated by two high/low impedance frequency selective surfaces and one resistive sheet. The constitutive parameters of the absorbing layers are optimized by means of the Particle Swarm Optimization method in order to maximize bandwidth and absorption rate of the structure in the GHz frequency range, where typically the first resonances of small enclosures occur.

Abstract
A procedure for the optimal design of compact and light-weight electromagnetic absorbers is presented. The absorbers are designed to damp resonances inside metallic enclosures on the basis of Jaumann's theory; several layers of lossy (artificial) dielectrics are separated by two high/low impedance frequency selective surfaces and one resistive sheet. The constitutive parameters of the absorbing layers are optimized by means of the Particle Swarm Optimization method in order to maximize bandwidth and absorption rate of the structure in the GHz frequency range, where typically the first resonances of small enclosures occur.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
