Abstract:
1. A method for determining the resistance of a material layer in accordance with the frequency of electromagnetic radiation impinging thereon, the method comprising: establishing a reference relationship, said reference relationship being a relationship between a transmission-related parameter and effective resistance, said transmission-related parameter characterizing electromagnetic radiation that passes through a uniformly resistant finitely thin material layer, said effective resistance characterizing said uniformly resistant finitely thin material layer through which said electromagnetic radiation passes, said establishing of a reference relationship including calculating a value of said transmission-related parameter for each of plural values of said effective resistance, wherein said effective resistance is assumed to be equivalent to the theoretical resistance of a uniformly resistant infinitely thin material layer insofar as each value of said effective resistance has associated therewith a value of said transmission-related parameter that is constant regardless of the frequency characterizing said electromagnetic radiation that passes through said uniformly resistant finitely thin material layer; performing at least one measurement of a value of said transmission-related parameter for a value of the frequency characterizing said electromagnetic radiation that passes through said uniformly resistant finitely thin material layer; and based on said reference relationship and said at least one measurement, finding at least one solution of a value of said effective resistance for a value of said frequency characterizing said electromagnetic radiation that passes through said uniformly resistant finitely thin material layer.
