“…These are the experimental studies to develop the new composite fillers and RAM. Saitoh et al [7] fabricated composites mixed with dielectric titanium oxide powders and magnetic carbonyl iron powders. They designed the double-layered microwave absorbers with the broad-band absorbing characteristics.…”

The ultimate aim of this study is the development of microwave absorbers containing both dielectric and magnetic lossy materials. Carbon nanofibers (CNFs) were used as dielectric lossy materials and NiFe particles were used as magnetic lossy materials. Total twelve specimens for the three types such as dielectric, magnetic and mixed radar absorbing materials (RAMs) were fabricated. Their complex permittivities and permeabilities in the range of 2~18 GHz were measured using the transmission line technique. The parametric studies in the X-band (8.2~12.4 GHz) for reflection loss characteristics of each specimen to design the single-layered RAMs were performed. The mixed RAMs generally showed the improved absorbing characteristics with thinner matching thickness. One of the mixed RAMs, S09 with the thickness of 2.00 mm had the 10 dB absorbing bandwidth of 4.0 GHz in the X-band. The experimental results for selected specimens were in very good agreements with simulation ones in terms of the overall reflection loss characteristics and 10 dB absorbing bandwidth.

“…The microwave engineer is forced to seek out proper trade-offs between contradictory goals whilst keeping the absorber physically realizable. Extensive experiments on double-layer microwave absorbers have been carried out in earlier research [10,11]. But the increase in the number of layers and subsequent advancements in material science have made it difficult to obtain an optimal result using conventional means of optimization.…”

Abstract-Microwave absorbers find a plethora of applications in the modern-day military and civil industries. This paper compares the performances of different variations of the Particle Swarm Optimization (PSO) algorithm to obtain optimal designs for multilayer microwave absorber over different frequency ranges, angles of incidence and polarizations. The goal of this optimization is to minimize maximum overall reflection coefficient of the absorber by choosing suitable layers of materials from a predefined database and simultaneously make the overall thickness the least practically possible. Numerical optimal results for each variation of the PSO are presented and the best results are compared with those existing in literature.
