摘要
In this paper, the response of a frequency selective surface (FSS) loaded with a nonlinear element is analyzed with the help of the harmonic balance method. The linear section of this configuration is composed of a freestanding FSS while its nonlinear section is a p-n diode biased with a DC voltage source. The method of moments is used to determine the impedance of the linear section at the fundamental frequency and its harmonics. The nonlinear section is modeled using the voltage-current relation of the diode. No simplifying assumption is made such that the analysis can be used to determine the steady state response of the nonlinearly loaded FSS for both large-signal and small-signal excitation.
