This paper presents the solution of a transient electromagnetic problem using COMSOL Multiphysics. The paper also presents a closed-form solution of a transient electromagnetic dipole. The computational solution compares well with a closed-form solution for this problem. This work ... Read More
Illegal immigrants and smugglers frequently use underground tunnels to avoid border security and checkpoints. In addition, the threat of international terrorism has recently made the effort to detect tunnels a national security priority. No single technology and sensing modality is ... Read More
The paper addresses a class of problems for modeling and consequently simulating the electromagnetic field radiation pattern from two arms Archimedes spiral coils. The frequency spatial wavelengths relative to the coil dimensions are in a range where the electromagnetic Maxwell’s ... Read More
The Radiofrequency Heating (RFH) is widely employed to heat biological tissue in different surgical procedures. Most models analyze the RFH employing a Parabolic Heat Transfer Equation (PHTE) based on Fourier's theory. The PHTE can be used for problems involving long heating times or low ... Read More
In this paper the propagation of a plane wave in a large lossy medium is presented. The investigated geometry consists in a wedgeshaped lossy dielectric embedded in a lossy material with different electromagnetic properties. The aim of the study is to determine the feasibility of a radar ... Read More
Cellular ceramic substrates are extensively used for pollution control systems in vehicles. The manufacturing process of them can involve microwave drying. In this study, we describe the development of a modeling framework for the microwave drying process of these substrates. The ... Read More
The electromagnetic fields have a great influence on the behavior of all the living systems. The human body itself is a source of naturally generated electric and magnetic fields. When external signals of comparable strength flows through the human body; the nature of changes that such ... Read More
The purpose of this paper is to illustrate the microwave coagulation therapy (MCT) that can be used mainly for the treatment of hepatocellular carcinoma. In this treatment invasive technique are used in which thin microwave coaxial antenna is inserted into the tumor and the microwave ... Read More
Hyperthermia is newly back in the interest of both, clinical and research oncologists, because of its properties to directly produce permanent damages of the treated tumors and to elicit important immunological responses against cancer cells by changing their immunogenicity. Microwave ... Read More
Raman spectroscopy is a commonly used tool in biodiagnostics and sensor technology. Surface-enhanced Raman scattering provides high signal enhancements especially at nanostructured metallic surfaces. In this paper the electromagnetic Raman enhancement from different metallic ... Read More
