Abstract-A method of solving the scattering problem for general multilayer anisotropic structures composed of conventional materials and metamaterial is presented. The analysis is based on calculation of the hybrid matrix of layers by means of a recursive algorithm. The method does not have the complexity and instability problems of other methods and is reliable in all cases. The zero reflection from stratified structures of conventional materials and metamaterials has then been introduced Various aspects of such a structure from the viewpoints of frequency and incident angle are presented and a rule for zero reflection from anisotropic medium is addressed. An interesting special case of total transparency is observed.

“…As shown in Figure 1, a plane wave is obliquely incident on the structure. In recent years, numerous methods have been employed for analyzing this structure [1][2][3][4][5][6][7][8][9][10][11][12]. Initial works on the subject were based on 4 × 4 characteristic matrix of a single anisotropic slab [1,2].…”

Abstract-Consider a plane wave incident on a multilayered anisotropic planar structure composed of conventional materials and metamaterials and surrounded by two half-spaces. In this paper, we aim to prove three theorems which indicate a kind of duality in these structures. Theorem 1: Assume that an arbitrarily polarized plane wave is obliquely incident on the structure. Now each layer is filled with by dual media according to the interchanges DPS ↔ DNG and ENG ↔ MNG. Then, the reflection (R) and transmission (T ) coefficients of the structure become the complex conjugates of their counterparts. Consequently, the reflected power and transmitted power from the structure are the same for the two dual cases of anisotropic media. Theorem 2: If the interchanges DPS ↔ DNG and ENG ↔ MNG are made in all the layers except in the half spaces on the two sides of the multilayer structure (which is more realizable), then the reflection coefficients become complex conjugates and the reflected power remains the same. Theorem 3: If the structure is backed by a perfect electric conductor and the media interchanges DPS ↔ DNG and ENG ↔ MNG are made in the layers, then the reflection coefficients of the two dual structures become complex conjugates of each other, and the reflected powers are equal. Independent of wave frequency, the number of layers, their thickness, and the type of polarization, these theorems hold true in case of any change in any of these conditions. In the last section, some examples are provided to verify the validity of the proposed theorems.

Abstract-Arrangements of bilayer anisotropic structures are inspected in this paper that manifest wonderful behaviors. One of these arrangements can pass TM & TE modes spontaneously in low frequencies and reflect them in higher frequencies and function as a low-pass filter. Another arrangement can reflect TE mode and pass TM mode in a particular frequency band and vice versa and function as a polarizer. All the analyses are based on the calculations of the hybrid matrix of layers by means of a recursive algorithm. Also the effect of the µ & ε tensors on the specifications of the filters is discussed.
