| Abstract | In this study, a novel dual-layer wide-angle metamaterial absorber with polarisation independence has been presented at three distinct frequencies. The proposed structure consists of dual stacked metal-dielectric layers which are terminated by the metal ground panel. The unit cell of the presented structure consists of three concentric 8-point star rings on the top surface of both dielectric layers exhibiting three absorption peaks of 98.96%, 98.7% and 99.43% under normal incidence at 1.8 GHz, 2.14 GHz and 2.57 GHz, respectively. The polarisation independence of the design has been validated by numerical simulation and practically verified using waveguide measurement technique. The structure displays high absorption of about 84% for transverse electric polarisation and over 97% under transverse magnetic polarisation up to 60° of oblique incidence. Furthermore, the effects of variation in physical design parameters on absorption response are investigated. The measurement exhibits good agreement with the simulated outcome. The presented structure has a thickness of 0.0294λ 0 with respect to the lower absorption band frequency. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
