FSS
Frequency Selective Surfaces (FSS) for defence and civil applications
Frequency Selective Surfaces (FSS) are periodic or quasi-periodic structures comprising arrays of lossy or conducting patterns and/or discrete components. Their dispersive properties can be tailored to meet specific requirements and they find application in many areas of electromagnetic engineering. This includes the design of antennas, metamaterials, radomes and Radar Absorbent Materials (RAM).
Q-par Angus Ltd has been involved in the production of custom FSS
products and FSS consultancy for many years. We have leading-edge
in-house analysis and design software, including QDAS.- QDAS (Q-par Dichroic Array Software), written by Dr Andrew Mackay, is intended for the analysis of transmission, reflection and grating lobe properties of composite structures including FSS. Demonstration software may be downloaded from our web site, including full documentation of the theory and use (see files under "Related Items"). It may also readily be used for the analysis and design of composite structures which do not contain FSS, for example multi-layer impedance matching and radar absorbent materials.
