The development of thin microwave absorber coatings that operates for a wide range of frequencies is still a challenging task. This work presents a technique of blending a fractal frequency selective surface (FSS) with single- and double-layer coatings. These coatings are comprised of well-optimized micrometer-sized (80-90 μm) and nano-sized (20-30(More)
The main aim of this study is to develop an cost effective microwave absorber that can provide wide absorption bandwidth (RL ≤ -10 dB) with less coating thickness (i.e., ≤ 2.0 mm). To achieve this, an electronic waste composite based microwave absorber blended with fractal frequency selective surface (FSS) is presented. The disassembled(More)
A thin radar wave absorber with wide bandwidth corresponding to reflection loss (RL) ≤ -10.0 dB is still very challenging job for researchers till date. In this paper, design of Frequency Selective Surface (FSS) loaded over single layer absorber is carried out with the help of Ansoft HFSS simulation tool.
