Designing a sub-wavelength array to change the direction of the radiation wave to a desired angle using variable Huygens surfaces [PDF]
AUT Journal of Electrical EngineeringSince Huygens structures with phase shift lead to beam rotation, this manuscript discusses a phase shifter structure for the Huygens surface based on Tapered Slot Transition in the frequency range of 9.95-10.2 GHz using varactor diodes.

Surface-Wave Losses of Coplanar Transmission Lines [PDF]
, 1983 Coplanar transmission lines lose energy to surface waves when the propagation constant of the surface-wave mode exceeds that of the transmission line. This happens when the substrate thickness is an appreciable fraction of a wavelength. The losses should

OPERATOR METHOD IN THE SCALAR WAVE DIFFRACTION BY AXIALLY-SYMMETRIC DISCONTINUITIES IN THE SCREEN
Radio Physics and Radio Astronomy, 2018 Purpose: The scalar wave diffraction by the annular slot in an infinitely thin screen is considered in case of Dirichlet and Neumann boundary conditions. Diffraction problem by a flat ring is also considered as a dual one.
