- Present the application of MTMs in the structure of the optical waveguides to realize integrated non reciprocal devices like isolators. The role of the MTMs parameters on the guided dispersion characteristic of the waveguide isolator is investigated by introducing several sets of negative permittivity and permeability with their products kept the same.
Optical sensor behavior under different stress effects. The effect of thermal-stress on the optical performance of nonlinear symmetrical sensor is studied. The mathematical forms of the dispersion equation and thermal stress sensitivity are analytically derived and plotted numerically. It is found that the thermal sensitivity of the sensor can be controlled by tuning the core size, by changing loading materials, and by carefully selecting the materials.
Study propagation of light through the proposed structure of the optical waveguide. Different factor has been taken into account to study waveguide structure. As an example, the behavior of electromagnetic field in a medium possessing a dielectric constant which is sinusoidally stratified along one coordinate sandwiched between a nonlinear cladding and a linear dielectric substrate. A first area of application is concerned with TE wave propagation through a compressible medium which is influenced by acoustic or other mechanical wave. As an example, the results are applicable to acoustically modulated plasma media in range of frequencies above plasma frequency. A second area of application regards the stratified medium as a first step in analysis of a sinusoidally modulated dielectric slab antenna. The power has been calculated by using Mathieu equation and using perturbation methods (Whittaker’s Method, and Multiple Scale Method). A simple numerical method has also been applied based on Mathieu function approach. Numerical results have been presented, we found that the approximate techniques are much easier and faster, and the considered wave guide structure represents a band reject filter.
Utilizing numerical simulations based on Monte Carlo Potts model to study the microstructural evolution in two-phase polycrystalline materials. These materials are composed of small grained which are “glued” together by interatomic forces. Polycrystals are intrinsically unstable. The instability is produced by grain boundary curvatures which lead to grain boundary migration. This boundary migration leads to minimization of interfacial energy and increasing the grain size. These changes affect physical and mechanical properties of materials such as their strength and creep resistance. Therefore understanding the microstructural evolution is very important in many practical and theoretical applications. Understanding the microstructural evolution in metals and ceramics helps to control the properties of these materials and enhance their performance in industrial applications.
