Nearly seven lakh Indians die of cancer, while over 10 lakh are newly diagnosed with some form of the disease every year. Surgical resection is not always feasible in patients with hepatocellular carcinoma. Microwave Coagulation Therapy (MCT) has been used as an alternative to resection and its efficiency has been evaluated in tissue microwave irradiation from a dipole antenna causes water ...

Previous studies proposed using bipolar radiofrequency ablation across two catheters placed on opposing surfaces of the ventricular wall to create transmural lesions. 2D and 3D models were built and solved with COMSOL Multiphysics software. With these models, it was possible to study the temperature distribution and lesion geometry (Figure), to compare the potential of two ways of applying ...
Analysis and Design of Antennas for an Implantable Medical Device System for Functional Electrical Stimulation
Alfred Mann Foundation for Scientific Research, Valencia, CA, USA
This poster outlines the results of finite element analyses to study the antenna radiation pattern of an implanted medical device. Also presented are simulation results used to design an electrically small antenna for a portable control unit that communicates with the implants over the Medical Micropower Network Frequency Range [413 MHz to 457 MHz]. Alfred Mann Foundation’s Functional Electrical ...

Introduction: Domestic microwave ovens are widely used to heat food products, because of rapid and convenient heating. Nonuniform heating is the biggest issue in microwave heating process, which also causes food quality and safety issues. Microwave heating models are promising tools to assist in developing food products that deliver uniform heating. Due to intensive heating, moisture evaporation ...
Analysis of a Planar Inverted-F Mobile Handset Antenna with Reduced Radiation Towards the Human Head
Cochin University of Science and Technology, Cochin, Kerala, India
This paper deals with the simulation and analysis of SAR and temperature distribution induced by a Planar Inverted-F Antenna on human head model using COMSOL Multiphysics® software. The goal of this paper is to compare the SAR and temperature distributions of omni-directional PIFA with that of a PIFA with reduced radiation towards human head. The two antennas are designed to operate at 900 MHz ...

This paper presents the electrical and thermal analysis of an OLED module. The OLED module consists of the OLED tile and the DC-DC converter incorporated in its backplane. The DC-DC converter is realized as an integrated circuit and its inductor is embedded in the the backplane. The DC-DC converter is highly efficient, but a fraction of the electrical power is dissipated in the integrated ...

Introduction: This study presents the 3D electromagnetic model in layered media using induction logging tool. This algorithm utilizes electromagnetic wave frequency domain (EWFD) interface of Maxwell equations. Electromagnetic methods are popular tools for the measurement of resistivity (or conductivity) of the Earth formation. The purpose of our study is to show the effect of conductivity and ...

Patch antennas are widely used in communications links with unmanned aerial vehicles. Their hemispherical send and receive patterns enable the systems to maintain radio frequency contact over a wide range of vehicular attitudes. A microstrip-fed design offers other attractive features including lightweight, inexpensive, and a 3-D structure that can be easily integrated into the fuselage. This ...
