"In this paper, three –layer slab waveguide is considered for the p-polarization whose free charge layer with a surface conductivity is assumed to exist at the two interfaces. The structure is then enhanced for sensing process by considering the di

In this paper, a four-layer slab waveguide sensor is proposed. The waveguide has the conventional structure of a substrate, a guiding film and a cladding. At the substrate-film interface, an additional layer is inserted which can be a material with n

In this work, one dimensional ternary photonic crystal is investigated as refractometric sensor. Using Chebyshev polynomials of the second kind, the transmission of an incident wave from a ternary photonic crystal is studied in details. The variation

A homemade spectroscopic ellipsometer is designed indigenously to characterize Si-SiO2 sample and two Poly (9-vinylcarbazole) (PVK) films. In the constructed ellipsometer, the polarizer and analyzer rotate in the same direction with the same angular

A slab waveguide structure consisting of five layers is studied for optical sensing applications. The five-layer waveguide structure has a guiding dielectric film, two left-handed material (LHM) layers and two dielectric layers as a substrate and a c

Two ternary photonic crystals are proposed for sensing applications. The first one is composed of an air layer as an analyte sandwiched between two double negative material (DNM) layers whereas the second one consists of an air layer sandwiched betwe

In a recent work, rotating polarizer compensator ellipsometer (RPCE) with a fixed analyzer was proposed. Three different ellipsometric configurations were presented by considering different speed ratios of the rotating elements. It was shown the spee

Ellipsometers have been widely used in thin film characterization. They have shown a high degree of accuracy. We here propose theoretically a rotating polarizer and analyzer ellipsometer at a speed ratio 1:1 with a fixed compensator placed just after

The theory of step-index waveguides is well-established. Most practical slab waveguide structures have a graded-index profile. The basic properties of graded-index planar waveguide structures are similar to those of step-index waveguides with subtle
