An absorbing boundary condition for computational electromagnetics called the perfectly matched layer (PML) was previously introduced [1]. In this paper, equivalent transmission line models for PML in both right-handed (RH) and left-handed (LH) materials are derived and proposed. Simulations employing the proposed model agree with those using the characteristic impedance of free space (η0). These models have application in numerical methods for reducing the calculation complexity and simulation time.
