3D Frequency Selective Structures: Opportunities and Challenges

Co-sponsored by: MTT/AP & ED/CAS

Abstract: 

Conventional frequency selective surface consists of a two-dimensional (2-D) periodic array of unit-cells, which are either printed on a dielectric substrate or etched out of a conductive surface. These simple 2-D surfaces suffer from poor frequency selectivity and unstable response under different incident angles. Recently, an innovative concept of three-dimensional (3D) frequency selective structure (FSS) was proposed to alleviate the disadvantages of traditional frequency-selective surfaces. The new type of 3-D frequency selective structure is composed of a 2D periodic array of vertically placed microstrip lines, which is very promising for the realization of compact high-performance FSSs. This talk will introduce the proposed 3-D frequency selective structure. Mode-matching formulation for analyzing the structure will be briefly presented and equivalent circuit model will be employed to explain the operating principle of these three-dimensional FSSs. A number of design examples will be presented to demonstrate the high performance filtering response of 3D FSSs. Possible research topics for further investigation are suggested and existing challenges are also mentioned at the end of the talk.
