Abstract
In this work, a design for a broadband multi-resonator metamaterial absorber (MTMA) for satellite communications is proposed. This design is based on both numerical and experimental data. Four resonators were used to achieve a broad absorption of more than 99% in the frequency range of 12–16 GHz. The electromagnetic properties (absorption, reflection and transmittance) of the MTMA were analysed and extracted. The parametric effects including the type of substrate, its thickness and the change of the resonator width on the absorption spectrum were studied. Also, surface currents, electric field and magnetic field distributions were investigated and presented at 12.75 GHz. Besides, the proposed design was fabricated by using the LPKFan ProtoMat E33 machine and tested by waveguide connected to a vector network analyzer. It was found that there is a good agreement between the simulation and experimental results. The proposed design can be used for different applications, especially for the application of satellite communications.
期刊介绍:
The Bulletin of Materials Science is a bi-monthly journal being published by the Indian Academy of Sciences in collaboration with the Materials Research Society of India and the Indian National Science Academy. The journal publishes original research articles, review articles and rapid communications in all areas of materials science. The journal also publishes from time to time important Conference Symposia/ Proceedings which are of interest to materials scientists. It has an International Advisory Editorial Board and an Editorial Committee. The Bulletin accords high importance to the quality of articles published and to keep at a minimum the processing time of papers submitted for publication.
