The problem of reflection and transmission of plane waves at an imperfect boundary between two thermally conducting micropolar elastic solid half spaces with two temperature is investigated. Amplitude ratio of various reflected and transmitted waves are presented when a set of coupled longitudinal wave (LD-wave) and thermal wave (T-wave) and a set of coupled transverse wave and microrotation wa...

In this paper, a recursive computation method is developed to derive the multiple reflections of nonuniform transmission lines. The true impedance profiles of the nonuniform transmission lines are then reconstructed with the help of this method. This method is more efficient than other algorithm. To validate this method, two nonuniform microstrip lines are designed and measured using Agilent ve...

We study analytically defect polariton states in Bragg multiple quantum well structures and defect-induced changes in transmission and reflection spectra. Defect layers can differ from the host layers in three ways: exciton-light coupling strength, exciton resonance frequency, and interwell spacing. We show that a single defect leads to two local polariton modes in the photonic band gap. These ...

A class of models is considered for a quantum particle constrained on degenerate Riemannian manifolds known as Grushin cylinders, and moving freely subject only to the underlying geometry: corresponding spectral analysis developed in detail view phenomenon transmission across singularity that separates two half-cylinders. Whereas classical counterpart always consists falling finite time along g...

Typically, many of the modern buildings have concrete walls constructed from cinder block walls, that have periodic nature in their relative dielectric constant. This periodic nature excites higher-order Floquet harmonic modes at microwave frequencies, which leads to the propagation of scattered waves along with non-specular directions. Periodic structures exhibit different behaviors when illum...

Interfaces play an essential role in phonon-mediated heat conduction in solids, impacting applications ranging from thermoelectric waste heat recovery to heat dissipation in electronics. From a microscopic perspective, interfacial phonon transport is described by transmission and reflection coefficients, analogous to the well-known Fresnel coefficients for light. However, these coefficients hav...

A second order finite volume scheme is considered [1]. The scheme includes total field scattered field formulation and a perfectly matched layer [2]. It was applied to evaluation of optical properties of photonic crystal waveguides [3]. Reflection and transmission coefficients were studied for a range of frequencies inside the photonic crystal bandgap for different configurations. Our results c...

The tail problem for the propagation of a scalar field is considered in a cosmological background, taking a Robertson-Walker spacetime as a specific example. The explicit radial dependence of the general solution of the Klein-Gordon equation with nonminimal coupling is derived, and the inapplicability of the standard calculation of the reflection and transmission coefficients to the study of sc...

This paper is about the scattering theory for one-dimensional matrix Schrödinger operators with a potential having finite first moment. The transmission coefficients are analytically continued and extended to band edges. An explicit expression given these extensions. limits of reflection at edges also calculated.

We analyzed capabilities and functionalities of a multisegment superlens recently suggested for long-distance transport of color images with subwavelength resolution. We studied the performance of threeand six-segment nanolens structures by analyzing numerically both transmission and reflection coefficients and by employing the full-wave simulations for a particular source arrangement. Our resu...
