Abstract

Many radiofrequency (RF) applications, including antenna-on-display and electromagnetic interference shielding, use thin meshed wires to form metal surfaces and ground planes, respectively, with good optical transparency. The characteristics of metal meshed-wire architectures are thus investigated in this paper to interpret their scattering behaviors, which allows the metal meshes to be properly applied to compose antenna radiators or shielding under a good light transparency consideration. They are resembled by an equivalent homogeneous dielectric substrate to simplify numerical simulation complexity. The equivalent conducting and dielectric properties of substrates are extracted from the propagating modes of the Floquet theorem. The equivalent conductivity and dielectric constant allow one to define a characteristic impedance to compute the reflection and transmission coefficients and therefore estimate the power efficiency for practical applications. Validations by numerical full-wave simulations using HFSS software at 28 GHz are shown to demonstrate their characteristics.

检验金属网格表面在不同的电磁屏蔽效果下保持良好的光学透明性

许多射频（RF）应用，包括天线显示和电磁干扰屏蔽，分别使用细网格线形成具有良好光学透明度的金属表面和接地面。因此，本文研究了金属网-线结构的特性，以解释其散射行为，从而使金属网在考虑良好的光透明度的情况下可以适当地应用于构成天线辐射体或屏蔽体。为了简化数值模拟的复杂性，它们被等效的均匀介质衬底所模拟。根据Floquet定理的传播模式，导出了衬底的等效导电性和介电性。等效电导率和介电常数允许定义一个特性阻抗来计算反射和透射系数，从而估计实际应用的功率效率。利用HFSS软件在28ghz下进行了全波数值模拟，验证了其特性。
