Design of Dual-Band Double Negative Metamaterials
D. Zarifi, E. Hosseininejad, A. Abdolali,
Volume 10, Issue 2 (June 2014)
Abstract
A dual-band artificial magnetic material and then a dual-band double-negative metamaterial structure based on symmetric spiral resonators are presented. An approximate analytical model is used for the initial design of the proposed structures. The electromagnetic parameters of the proposed metamaterial structure retrieved using an advanced parameter retrieval method based on the causality principle show its dual-band nature at microwave frequencies.
Plane Wave Reflection and Transmission from Uni- and Bi-Axial Chiral Slabs
D. Zarifi, M. Soleimani, A. Abdolali,
Volume 10, Issue 4 (December 2014)
Abstract
In this paper, the propagation of electromagnetic waves through an infinite slab of uni- or bi- axial chiral medium is analytically formulated for an arbitrary incidence using 4×4 matrix method. In this powerful method, a state vector differential equation is extracted whose solution is given in terms of a transition matrix relating the tangential components of electric and magnetic fields at the input and output planes of the uni- or bi- axial chiral layer. The formulas of the reflection and transmission are then derived. Also, the presented method is verified by some typical examples and the results are compared with the results obtained by the other available methods.
