| dc.description.abstract | In certain microwave applications, it is required to rotate the plane of polarization of
a linearly polarized wave or beam by some desired angle relative to a fixed antenna or
waveguide feed. Hence we study Polarization Rotation properties of one class of Polarization
Rotators. Here we use twisted anisotropic medium to achieve desired rotation of the
incident plane wave. We model a stack of uniaxial anisotropic layers, with their optic axis
gradually rotated. A numerical study is made on this configuration for various structural
parameters like thickness of each uniaxial layer, overall length of the structure, refractive
indices, and angle of rotation. Prom our study, we arrive at an expression, which has to
be satisfied by the overall length of the structure for effective polarization rotation. An
approach to fabricate artificial uniaxial anisotropic medium is also presented. | |
