Anew absorber design using metamaterials for thermo photovoltaic applications is simulated here. Conventional absorbents normally have narrow band-widths and/or sensitive-polarization. Alternatively, the present study shows the possibility to find an infrared absorber structure with optimal characteristics involving a metal-dielectric. A combination of two resonators, circular cavity in a square metallic patch, laid on a dielectric substrate is proposed here. With this design, the results show that wide-band absorption can be achieved. The absorption bandwidth can be widened from 57.2 to 95.4 THz, with absorption efficiency higher than 90%. This structure design is polarization-insensitive to incident electromagnetic wave angles. These new features make the new absorber potentially useful in thermo-photovoltaic conversion applications. © 2017, Springer Science+Business Media, LLC, part of Springer Nature.
