Outline
In response to the low detectability requirements of micro radar detectors, a hybrid polarization-frequency selective rasorber (PFSR) is proposed. Firstly, based on the equivalent circuit analysis method derived from transmission line theory, the mechanism for achieving wave absorption and transmission compatibility is explored. Furthermore, by employing a bilaterally asymmetric loading approach with resistive sheet, the polarization-selective functionality of the transmission window is realized. Finally, through a hybrid design of resistive sheet, the challenge of achieving wideband absorption and transmission compatibility is addressed. Simulation results indicate that when TE waves are incident, this structure exhibits integrated functionalities with wave transmission in the frequency range of 6.8 to ${7.8}\mathrm{{GHz}}$ and low scattering across 2.2 to${18.0}\mathrm{{GHz}}$. In contrast, when TM waves are incident, it demonstrates an effective wave-absorbing capability with low scattering in the frequency range of 3.2 to 18.0 GHz. This design offers a viable solution for enhancing wideband low detectability in flight communication platforms such as satellites.
