“…In our previous work, we investigated the polarization independency of the cross-metallic absorbers. 25 In fact, we demonstrated that the electromagnetic wave polarization has a big effect on the absorption coefficient of a cross metallic metasurface. For cross unit cell, the linear polarization gives a better Absorption coefficient for high frequencies (wide band) contrary to circular polarization, which gives a maximum absorption for only one frequency (very selective).…”

We present a rigorous study of the reflection, transmission and absorption properties of cross metallic absorbers for terahertz broadband application. The quantitative analysis given in this study allows us to design terahertz absorbers for monolithic and multilayer terahertz detectors. The analytical modeling presented in this paper can be used as a modeling support to optimize the design of cross metallic absorbers. The presented theoretical models approach the reflection, transmission and absorption problem from different points-ofview yielding distinct sets of equations connecting the different parameters of the absorber. The results show the necessity to take into account all the dimensions of the absorbers to design the optimized structures. In fact, the results indicate that the optimum dielectric thickness to have the best absorption changes according to the geometry of the cross metallic absorber. A good agreement is shown among the analytical, finite element, and experimental results.

“…As a subwavelength structure, the meta-atom can exhibit electrical polarization and magnetic polarization defined by the material and geometry ( Meinzer et al., 2014 ). The metasurface can be formed by periodic arrays of meta-atoms, providing an ideal platform for the realization of THz functional devices ( Zhang et al., 2008 , 2013 ; Landy et al., 2008 ; Ben Mbarek et al., 2019 ; Wang et al., 2020 ; Wu et al., 2020 ; Rouhi et al., 2018 ; Shabanpour et al., 2020 ; Cong and Singh, 2020 ; Cong et al., 2018 ). Nevertheless, the properties of most metasurfaces are restricted by the fixed geometric parameters of meta-atoms.…”
