In this study, wave interaction with double-negative (DNG) and double-positive (DPS) plates is presented. Theoretically, the structure is composed by DNG and DPS plates with different material properties and thicknesses forming an N-tier structure. The DNG plates are described by using the Lorentz and Drude media parameters while the DPS plates are defined by known dielectric materials. The incident electric field is assumed to be a monochromatic plane wave with any arbitrary polarization. After obtaining the electric and magnetic fields both inside and outside the plates and imposing the boundary conditions, the reflected and transmitted powers are calculated using the transfer matrix method in order to observe their behaviors. In this paper, the frequency response of the DNG and DPS plates is deeply analyzed both analytically and numerically. Finally, the computations of reflected and transmitted powers are analyzed numerically with the purpose of designing efficient filters at the microwave, millimeter wave, and optical frequency regions.
