Electromagnetic wave propagation through frequency-dispersive and lossy double-negative slab

Abstract

This study presents the electromagnetic wave propagation through the frequency-dispersive and lossy double-negative slab embedded between two different semi-infinite media. The double-negative slab is realized by using two models, the Lorentz and Drude medium models. The properties and the required equations for the frequency-dispersive and lossy double-negative slab, the Lorentz medium and Drude medium are given in detail. After the construction of the problem, the reflection and transmission coefficients are derived for both TE and TM waves. Then, the reflected, transmitted and loss powers are determined using these coefficients. Finally, in the numerical results, the mentioned powers for TE and TM waves are computed and illustrated as a function of the incidence angle, the frequency and the slab thickness when the damping frequency changes.

Transmission Tunneling Through the Multilayer Double-Negative and Double-Positive Slabs

“…Note that the real part of the complex wave number has to be negative for DNG slab which is a common information known in the literature [15]. The DNG slabs are defined using frequency dispersive Lorenz [12] and Drude [13] models in which they can provide simultaneously negative permittivity and permeability at a certain frequency band.…”

“…In the mentioned models, the constitutive parameters can be arranged to be simultaneously negative below the electric and/or magnetic plasma frequency. Accordingly, these models can theoretically be used to designate a metamaterial (MTM) system (including multilayer MTM structure) for creating/realizing new functional devices [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. Additionally, the Lorentz and Drude models as MTMs have been utilized in many studies in which one of them is the multilayer MTM system with the application of EM filters [12].…”

Reflection and transmission from left-handed material structures using Lorentz and Drude medium models

“…Reflection and transmission from a frequency−dispersive and lossy LHM slab embedded between two semi−infinite dielectric media were investigated [29]. Effects of loss factor on reflection and transmission through a LHM slab were studied [30].…”

Multilayer System of Lorentz/Drude Type Metamaterials With Dielectric Slabs and Its Application to Electromagnetic Filters

“…Lossy and lossless Lorentz/Drude types of DNG metamaterials are characterized theoretically, used in several experiments, and fabricated for new devices in these studies. For example, wave propagation through the double negative Lorentz/Drude slab embedded between two different dielectric media is studied in [6,9,14,23]. Lorentz types of DNG (LDNG) metamaterials have frequency dispersive parameters, and they can be fabricated using a mixture of conductive spirals or omega particles on printed circuit boards [7,9,18].…”
