A survey of theoretical models for terahertz electromagnetic metamaterial absorbers
TL;DR: In this article, the authors reviewed four prevalent theoretical approaches which include effective medium theory, transmission line modelling, coupled mode theory, and interference theory for metamaterial absorbers and discussed that impedance matching is the crucial condition for perfect absorption.

Analysis of the thickness dependence of metamaterial absorbers at terahertz frequencies
TL;DR: Interference theory is employed to obtain an analytical expression for the spacer thickness needed to maximize the absorption at a given frequency and observes that the absorption peaks redshift as the spcer thickness is increased, in excellent agreement with the analysis.
