    • Analytic solution to field distribution in one-dimensional inhomogeneous media 

      Gric, Tatjana; Cada, Michael (Optics communications, 2014)
      A new general expression of a solution to Maxwell׳s equations derived recently has been applied to a 1-D inhomogeneous medium. It is shown that it solves any inhomogeneous refractive index profile. Its main advantage is ...

    • Analytical electric field intensity profile in diffused channel waveguides 

      Gric, Tatjana; Cada, Michael (Journal of electromagnetic waves and applications, 2015)
      A novel analytic solution to field distribution is used to calculate the intensity distribution for channel waveguides with a two-dimensional diffusion-type refractive index profile. Composition profiles for the waveguides ...

    • Challenge of inhomogeneous waveguides analysis 

      Gric, Tatjana; Eldlio, Mohamed; Cada, Michael (Photonics North 2014 : proceedings of SPIE, Montreal, Canada, May 28-30, 2014 / Editor(s): Steve MacLean; David V. Plant, 2014)
      Optical waveguides have been a subject of an intensive theo retical research, resulting in applications in several fields, and stimulated research in integrated optics. Homogeneous dielectric waveguides and their properties ...

    • Effect of filling the surface texture with metamaterial on spoof surface plasmon dispersion 

      Gric, Tatjana; Pistora, J.; Cada, Michael (Optical and quantum electronics, 2016)
      Herein we present an approach on expansion of the work by Pendry, who put forward the idea of spoof surface plasmons in conducting films as a way to engineer surface plasmon polaritons (SPPs) dispersion curves. Investigating ...

    • Hyperbolic metamaterial interface: propagation of surface waves 

      Gric, Tatjana; Cada, Michael; Pistora, Jaromir (Global Journal of Researches in Engineering: J General Engineering, 2016)
      Herein we study propagation of surface waves at a boundary of an isotropic media and a multilayered hyperbolic metamaterial. The structure dispersion is discussed for various cases of a hyperbolic metamaterial. It is ...

    • Propagation of surface waves formed at the interface between hyperbolic metamaterial and highly doped semiconductor 

      Gric, Tatjana; Cada, Michael; Pistora, J. (Optical and quantum electronics, 2016)
      We provide an analysis of surface-wave propagation at a boundary between a semiconductor and a multilayered hyperbolic metamaterial. In particular we analyzed the structure dispersion for various cases of a hyperbolic ...

    • Spoof plasmons in corrugated metamaterials 

      Gric, Tatjana; Cada, Michael (International Journal of Research Studies in Electrical and Electronics Engineering (IJRSEEE), 2016)
      To obtain the eigenmodes of the electromagnetic field at a periodically corrugated metamaterial we consider a theory of spoof plasmons propagating on metamaterial perforated with planar periodic grooves. We present the ...

    • Spoof plasmons in corrugated semiconductors 

      Gric, Tatjana; Wartak, Marek; Cada, Michael; Wood, John; Hess, Ortwin; Pistora, Jaromir (Journal of electromagnetic waves and applications, 2015)
      We report on a theoretical investigation of the dispersion relation of surface plasmon polaritons (SPPs) on a periodically corrugated semiconductor surface. We assumed Drude’s permittivity model of the semiconductor, which ...

    • Spoof plasmons in real metals with an arbitrary shape of perforation 

      Gric, Tatjana; Wartak, M.S.; Cada, Michael (Proceedings of SPIE, 2014)
      Spoof plasmons are bound electromagnetic waves (EM) at frequencies outside the plasmonic range mimicking (“spoofing”) surface plasmons (SPs), which propagate on periodically corrugated metal surfaces. In recent years, ...
