The transverse magnetic Gaussian beam diffraction from a finite number, equally spaced and rectangular cross section dielectric cylinder row is studied. The infinitely long cylinders' axes are perpendicular to the beam's direction of propagation. The cylinder row, with dielectric constant εc=nc2, is treated as a periodic inhomogeneous film, with period ax… (More)

The reflectivity R of a multilayer stack and its first and second derivatives with respect to the phase change are derived here by a recursive method. These equations improve the determination of stability conditions for coatings and widen the applications to treatments other than antireflection coatings, as reported by Mouchart [Appl. Opt. 16, 2486… (More)

We report experimental results of the resonant scattering of light from a prism-glass/Ag/MgF2/air system with use of the attenuated total reflection technique for p and s polarized light. Two MgF2 film thicknesses were used. The system with the thinner dielectric layer supports two transverse magnetic (TM) and two transverse electric (TE) guided modes at a… (More)

By using an integral method and the second Green identity we solve numerically the Helmholtz equation. With this method we determine the average band structure and average field distribution within the unit cell of a two-dimensional photonic crystal with a Gaussian statistic on the surface roughness, refractive indices and filling fractions.

We theoretically studied the influence of an infinite set of waveguides on the evanescent field of Bloch waves at the surface of a one-dimensional photonic crystal (PC) excited by a TE Gaussian beam undergoing total internal reflection. The set of waveguides is regarded as a periodic inhomogeneous medium with period a. Numerical results are presented for… (More)

Scattering of s-polarized electromagnetic planes waves from a film, with a shallow random rough one-dimensional surface, bounded by vacuum and a perfect conductor is calculated. An integral equation that relates the amplitude of the scattered field to the incident wave is found by use of the Rayleigh hypothesis. The integral equation is solved numerically… (More)
