In this paper we have studied the effect of magneto-static field onpropagation of thermal wave generated in metal by pulsed laser. In fact this interactiongenerate acoustic wave in different mechanisms. However, always the commonmechanism in the interactions of laser pulse and metal is the thermo-elastic wavegeneration. Applying the suitable magneto-static field on the s...

   Quantum-dot Cellular Automata (QCA) technology is a solution for implementation of the nanometer sized circuits and it can be a suitable replacement for CMOS. Similar to CMOS technology, designing the basic computational element such as adder with the QCA technology is regarded as one of the most important issues that extensive researches have been done about it. In this paper, a new eff...

A device-level simulation is presented for studying wave propagation along metal–insulator–semiconductor interconnects. A set of nonlinear equations is first formulated by combining the motion equations of charged carriers and Maxwell’s equations. The set of nonlinear equations is then transformed into the frequency domain, which leads to sets of nonlinear equations for the fundamental mode and...

Introduction: Ultra-wideband antenna arrays achieve operation over bandwidths of 4:1 or more. These arrays are traditionally costly due to high element counts. Wavelength-scaled arrays (WSAs) have the same aperture size and bandwidth as traditional ultra-wideband arrays, but have significantly fewer elements. Using scaled elements of three different sizes, an 8:1 bandwidth WSA has fewer than 18...

This paper is concerned with the simulation of periodic traveling deep-water freesurface water waves under the influence of gravity and surface tension in two and three dimensions. A variety of techniques is utilized, including the numerical simulation of a weakly nonlinear model, explicit solutions of low-order perturbation theories, and the direct numerical simulation of the full water wave e...

The significant effect of waves on coastal and marine activities urges the precise identification of wave characteristics using field measurements, theoretical studies, physical modeling or numerical simulations. In order to study thoroughly the wave climate in the Caspian Sea, a wave modeling and hindcast project was performed by Iranian National Center for Oceanography. In this study, one of ...

This study presents a theoretical design study of a novel three-dimensional micromachined hemispherical shell antenna for ultra-wideband millimetre-wave imaging applications. The antenna is composed of a hemispherical metallic shell which is suspended on top of a high-resistivity silicon substrate using a thin silicon stem. The antenna exhibits two different operational modes and an exceptional...
