Retrieval Approach for Determination of Forward and Backward Wave Impedances of Bianisotropic Metamaterials

Abstract

Abstract-A simple approach is proposed for retrieving the forward and backward wave impedances of lossless and lossy bianisotropic metamaterials. Compared with other methods in the literature, its main advantage is that forward and backward wave impedances can be uniquely and noniteratively extracted. It has been validated for both lossless and lossy bianisotropic metamaterials by performing a numerical analysis. The proposed approach can be applied for checking whether the metamaterial structure shows the bianisotropic property by monitoring forward and backward wave impedances, since the forward and backward wave impedances of a metamaterial structure depend on different polarizations of the incident wave.

Application of a Useful Uncertainty Analysis as a Metric Tool for Assessing the Performance of Electromagnetic Properties Retrieval Methods of Bianisotropic Metamaterials

“…There are some available methods in the literature for determining the electromagnetic properties of MMs [10][11][12][13][14][15][16][17][18][19][20][21][22][23]. While some of them are suitable for numerical simulations, others are appropriate for analytical models.…”

Determining the Effective Electromagnetic Parameters of Bianisotropic Metamaterials With Periodic Structures

“…Some other investigations of the bianisotropic materials also appear in recent years [18][19][20][21]. In this paper, we propose a straightforward approach to retrieve the effective electromagnetic parameters of a bianisotropic material from S parameters using the transfer-matrix method.…”

Design Analysis of New Metamaterial for Em Absorption Reduction

“…Typically, ε and µ are both positive in ordinary materials. The negative permittivity can be obtained by arranging the metallic thin wires periodically [18][19][20][21][22][23][24][25]. Alternatively, an array of split ring resonators (SRRs) can display negative effective permeability.…”
