Abstract
We analyze a random RLC lattice model for the optical properties of a two-dimensional normal metal-insulator composite, using the Y − Δ transformation algorithm developed by Frank and Lobb. Within such a model, the surface plasmon resonances of a Drude metal-insulator composite are modeled by the ac resonances of a random resistor-inductor-capacitor (RLC) network. The real part of the effective conductance is found to show a broad surface plasmon resonance peak below and above the threshold. An effective-medium (EM) calculation is in excellent agreement with the results of the simulations. We also calculate the far-infrared absorption in a model composite of normal metal and superconductor, using a lattice model. The absorption shows a strong absorption below the superconducting energy gap. An approximate calculation based on the EMA is again in excellent agreement with these results.
