Moreover, the proposed 3D waveguide can be efficiently coupled to conventional microstrip line waveguides. Our results (based on the numerical method) demonstrate that SMPs based on semiconductors offer a promising approach to creating devices with new functionalities in the terahertz regime below the ...
One of the most important properties is the orbital angular momentum [43,44], which is determined by the order of the optical vortex (topological charge). A distinctive feature of an optical vortex beam is the presence of vortex phase singular points at which the phase is not defined, and ...
