چکیده
|
Herein, an integrated multifunctional design for simultaneous perfect absorption and polarization conversion is proposed that worked in the ku band: the proposed structure consisted of two asymmetric dielectric semi-rings which are supported on a ground plane by two dielectric cylinders with different heights. simulated results demonstrate that unity absorption and linear cross-polarization conversion can be integrated into one multifunctional structure: absorption and polarization conversion operate at different frequencies. furthermore, these different functions under the different polarized modes (te and tm) are integrated into the single structure without adjusting any parameters, while also at a large range of incident angles. the integrated design is more conducive to the miniaturization and multi-functionality of devices and there are also practical applications in other areas.
