Hybrid-mode analysis of circular waveguide with chiral dielectric lining for dispersion characteristics for potential application in broadbanding a gyro-traveling-wave tube

Complex Bianisotropy Effect on the Propagation Constant of a Shielded Multilayered Coplanar Waveguide Using Improved Full Generalized Exponential Matrix Technique

“…The particular properties of bianisotropic media arise from a coupling between the electric and magnetic fields that can be explicitly described by general constitutive relations. Due to their diversity, they have found many potential applications from microwaves to optical frequencies such as polarization transformers, directional couplers, antenna and transmission line substrates, antenna radomes, radar systems, chiral waveguides and others [8][9][10][11][12][13].…”

“…Several studies have been conducted to characterize the electromagnetic behavior of bianisotropic media [14][15][16][17][18], ferrites [19], metamaterials [20], chiral [21,22], nonreciprocal [23] for simple and complex dielectric based microwave planar structures using numerical and analytical methods [8,14,17,20,[24][25][26][27][28][29][30][31][32][33][34][35]. In [8] and [35], the method of lines is used to analyze planar transmission lines with conductor losses and to analyze integrated optical waveguide structures, respectively. In [17] and [20], the transmission line matrix (TLM) method is used for modeling dispersive chiral media and the analysis of dispersion in metamaterials.…”

Calculation of the Electromagnetic Field of a Rectangular Waveguide With Chiral Medium

“…Metamaterials are artificial substances whose interaction with the electromagnetic field is significantly different from the interaction of ordinary natural materials. Among the new metamaterials of particular interest are bianisotropic, biisotropic, in particular, artificial media with strong chirality [1][2][3][4][5][6].…”

“…Biisotropic media are the most common type of linear isotropic medium. The main difference of the biisotropic medium from the usual dielectric or magnet is the presence of a magneto-electric coupling, due to which additional terms appear in the material equations [1,2]:…”

“…Artificial biisotropic and bianisotropic media are created by placing metallic resonant particles ("molecules") in a normal medium, whose dimensions are smaller than the wavelength of electromagnetic radiation in a certain range [1,2].…”
