Auto assembled Ag-ZnO [1] star shaped nanostructures depicted in figure 1, presents their natural electromagnetic resonance at 60 THz. In this work we present that is possible to change this value by covering it with a variable in thickness layer of gold. The analysis is performed by ... 詳細を見る
The antenna pattern synthesis problem is of the utmost importance in almost every kind of antenna applications. Therefore, a very large number of contributions have appeared on this subject. A number of different implementation methods are well known, and widely used. In this paper we ... 詳細を見る
While low frequency light is poorly transmitted through an aperture in a conductive thin film, in the phenomenon known as extraordinary optical transmission (EOT), a narrow band of selected frequencies are transmitted when incident on an array of subwavelength periodic apertures where ... 詳細を見る
Radiofrequency (RF) tissue ablation is commonly used to treat medical conditions involving dysfunctional tissue especially in the heart, kidneys, lungs, bones, or liver. An electrode at the tip of a catheter delivers high frequency current (350-500 kHz) to the targeted tissue causing it ... 詳細を見る
INTRODUCTION. In a magnetic resonance imaging (MRI) system (see Fig. 1), it is necessary to excite the nuclei of a patient into coherent precession for imaging. This requires coupling between the nuclei and a source of radio frequency (RF) power (the transmitter). To receive a ... 詳細を見る
The measurement of dielectric constant at frequencies of 20 GHz or greater is important for specifying the optical properties of materials at millimeter wavelength. One method of measurement uses a resonant cavity containing a sample of the material, and relates the resonant frequency ... 詳細を見る
Particle accelerator technology evolves gradually towards improving reliability and efficiency of the accelerator machines, which would reduce their cost for current applications and even make them more accessible to new industrial applications. RF cavities are utilized in particle ... 詳細を見る
A genetic algorithm was programmed in MATLAB® software and linked to the COMSOL Multiphysics® software with the COMSOL LiveLink™ for MATLAB® to optimize the geometry of an optical antenna (nanoantenna). The proposed computational model demonstrated that nanoantenna geometries does not ... 詳細を見る
The multiphysics analysis of a 130 GHz klystron is described in this paper. Critical quantities are exposed to multiple physics effects acting on narrow dimensions modified by power dissipations. The proposed device uses an integrated injection/bunching section described in last COMSOL ... 詳細を見る
Electromagnetic and thermal simulations are achieved using COMSOL Multiphysics® with 2D axisymmetrical finite–element method for a percutaneous microwave hyperthermia system with ex–vivo experiments on different biological tissues. Temperature variation and distribution are studied in ... 詳細を見る
