Patent ID: 7792644

Claim:
A method for analyzing a frequency selective surface wherein at least one act of the method is performed by a processing system, comprising: defining a frequency range comprising a plurality of frequency values within the frequency range; determining a frequency dependent permittivity for each of the plurality of frequency values across the frequency range for a substrate included in a frequency selective surface; determining a frequency dependent conductivity for each of the plurality of frequency values across the frequency range for a conductive material included in the frequency selective surface; analyzing the frequency selective surface using a method of moments analysis at each of the plurality of frequency values for an incident electromagnetic energy impinging on the frequency selective surface by including the frequency dependent permittivity and the frequency dependent conductivity in the method of moments analysis to develop a frequency response function; defining a geometry of the frequency selective surface comprising the substrate and the conductive material disposed on the substrate to form an array of resonance elements; and determining an emissivity of the frequency selective surface at each of the plurality of frequency values using the frequency dependent permittivity properties of the substrate and the frequency dependent conductivity properties of the conductive material.
