摘要

提出了一种有效的频率选择曲面介质建模方法。该方法只需检索一次有效介质的电磁参数，即可计算任意入射下的反射/透射系数。与以往的工作相比，该方法将复杂的FSS等效为单层或多层介质板，减少了建模和计算时间。为了验证，我们建立了网格化方形环路FSS的有效介质模型，并得到了建模经验公式。计算结果与CST法吻合较好，优于等效电路法。

Effective medium modeling method for gridded square loop FSS

This paper presents an effective medium modeling method for frequency selective surface (FSS). The proposed method only retrieves the electromagnetic parameters of the effective medium once, then the reflection/transmission coefficients under arbitrary incidence can be calculated. Compared with previous works, the proposed method reduces the modeling and calculation time by equating the complex FSS to single-layer or multi-layer dielectric slabs. For verification, we built an effective medium model for gridded square loop FSS and obtained a modeling empirical formula. The calculated results are in good agreement with CST and better than the equivalent circuit method.

期刊介绍： An aim of ELEX is rapid publication of original, peer-reviewed short papers that treat the field of modern electronics and electrical engineering. The boundaries of acceptable fields are not strictly delimited and they are flexibly varied to reflect trends of the fields. The scope of ELEX has mainly been focused on device and circuit technologies. Current appropriate topics include: - Integrated optoelectronics (lasers and optoelectronic devices, silicon photonics, planar lightwave circuits, polymer optical circuits, etc.) - Optical hardware (fiber optics, microwave photonics, optical interconnects, photonic signal processing, photonic integration and modules, optical sensing, etc.) - Electromagnetic theory - Microwave and millimeter-wave devices, circuits, and modules - THz devices, circuits and modules - Electron devices, circuits and modules (silicon, compound semiconductor, organic and novel materials) - Integrated circuits (memory, logic, analog, RF, sensor) - Power devices and circuits - Micro- or nano-electromechanical systems - Circuits and modules for storage - Superconducting electronics - Energy harvesting devices, circuits and modules - Circuits and modules for electronic displays - Circuits and modules for electronic instrumentation - Devices, circuits and modules for IoT and biomedical applications
