Electromagnetic Guided Wave in Goubau Line with Graphene Covering: TE Case

Publikováno v: Photonics, Vol 10, Iss 11, p 1205 (2023)

This paper focuses on the problem of monochromatic terahertz TE-polarized wave propagation in a special type of circle cylindrical waveguides, the so-called Goubau line. The outer shell of the waveguide is covered with graphene characterized by compl

Transverse Electric Guided Wave Propagation in a Plane Waveguide with Kerr Nonlinearity and Perturbed Inhomogeneity in the Permittivity Function

Autor: Anna Dyundyaeva, Stanislav Tikhov, Dmitry Valovik

Publikováno v: Photonics, Vol 10, Iss 4, p 371 (2023)

The paper focuses on the problem of transverse electric wave propagation in a plane-shielded waveguide filled with a nonhomogeneous and nonlinear (Kerr) medium. The nonlinear part of the permittivity is characterized by the Kerr law in the focusing r

On a Different Vision of Kerr Law in Nonlinear Optical Waveguide Theory

Autor: Yury Smirnov, Stanislav Tikhov, Dmitry Valovik

Publikováno v: Photonics, Vol 9, Iss 12, p 901 (2022)

This paper focuses on electromagnetic transverse-electric wave propagation in a planar shielded waveguide filled with nonlinear medium. Instead of using the standard local Kerr (cubic) nonlinearity, we suggest a (nonlocal) modification of this law. I
