Abstract

A method for selective control of multiband filtering of microwaves in the 3–6 GHz range has been proposed and tested. It is based on the use of a metastructure as one of the reflectors of a Fabry–Perot cavity of a modified h-plane waveguide-tee interferometer. The metastructure consists of an array of linear resonant wires in combination with an orthogonally and asymmetrically located copper strip with a break, loaded with a control element (varactor or fixed capacitance). The possibility of selective frequency and depth control of the interference stop-band in a three-band Fabry–Perot cavity and a modified seven-band tee interferometer has been discovered. The retuning of the cavity and interferometer bands is shown to be associated with the influence of resonance in a metastructure and occurs when the resonance frequency in the metastructure approaches the corresponding interference fringe.

在具有金属线的元结构作为法布里-珀罗腔反射器的元干涉仪中的干涉图控制

摘要

已经提出并测试了一种用于选择性控制3-6 GHz范围内的微波的多频带滤波的方法。它基于使用元结构作为改进h的Fabry-Perot腔的反射器之一平面波导三通干涉仪。上层结构由线性谐振金属丝阵列与正交且非对称定位的带断裂的铜带组成,并装有控制元件(变容二极管或固定电容)。发现了在三波段法布里-珀罗腔和改进的七波段三通干涉仪中选择性控制频率和深度的干扰阻带的可能性。谐振腔和干涉仪频段的重整显示与基础结构中的共振影响相关,并在基础结构中的共振频率接近相应的干涉条纹时发生。
