In the past few years, radio frequency (RF) devices, which are usually used in the vicinity of a human body, are increasing. The health effects of the electromagnetic (EM) waves from RF devices on the human body are dependent on the frequency and strength of the waves. The absorbed RF EM energy mainly contributes to tissue heating. The specific absorption rate (SAR) has been used as the standar...

The TEM3P module of ACE3P, a parallel finite-element electromagnetic code suite from SLAC, focuses on the multiphysics simulation capabilities, including thermal and mechanical analysis for accelerator applications. In this paper, thermal analysis of coupler feedthroughs to superconducting rf (SRF) cavities will be presented. For the realistic simulation, internal boundary condition is implemen...

During an MR procedure, most of the transmitted RF power is transformed into heat within the patient's tissue as a result of resistive losses. Not surprisingly, the primary bioeffects associated with the RF radiation used for MR procedures are directly related to the thermogenic qualities of this electromagnetic field. This review article discusses the characteristics of RF energy-induced heati...

This paper concerns a new method for projectile disposal by emptying the explosives in projectiles with electromagnetic heating. It explains basic principles of technology via A multiphysical analysis model coupled an electromagnetic, thermal, fluid and phase transition is established, explosive melting simulation conducted based on this model. The dynamic process from solid to liquid simulated...

In respect of imaging quality and patient safety, temperature rises and SAR distributions, which are caused by interaction of the applied electromagnetic fields during MR exams, are of high interest for implants in MR tomography [1]. High local SAR values are equivalent to high local temperature increases [2]. For developing support for radio frequency (RF) induced heating experiments, SAR valu...

This paper presents both theoretical and experimental work on the heating of carbon fiber reinforced plastic (CFRP) by millimeter (mm)-waves. In contrary to the standard methods using autoclaves, samples are cured using a 30 GHz gyrotron furnace. Heating experiments, showing the strong influence of the fiber orientation in the samples on their heating behavior are performed with cured samples i...

Induction heating furnaces are employed for vacuum distillation process to recover and consolidate heavy metals after electrorefining operation. Induction heating furnaces of suitable heating rates are required to be developed for this purpose. Hence it is planned to set up a mock-up induction furnace which will simulate the conditions to be realized in actual induction heated vacuum distillati...

The present study investigated the effect of different factors on temperature distribution within a spherical object in a parallel plate radio frequency (RF) heating system. A finite element-computer simulation program FEMLAB was used to solve the electromagnetic and Navier�Stoke equations for developing a model to study the effect of dielec� tric properties of a model fruit and its surrounding...
