Analysis of Coupled Electromagnetic and Thermal Fields in the Instationary Case
2001The handling of mission-critical devices, e.g. electro-mechanical actuators, requires an exact calculation of the electromagnetic field. For this task, thermal influences on the electrical behavior cannot be neglected. Furthermore stationary solutions will no longer be sufficient for the coupled problem.

Modeling of Mutual Coupling Between Electromagnetic and Thermal Fields in Microwave Heating
2007 IEEE/MTT-S International Microwave Symposium, 2007This paper presents the analysis and modeling of the mutual coupling between thermal and electromagnetic fields. During the microwave heating process the microwaves are dissipated to heat due to the dielectric losses of the medium. The heat propagation inside the medium depends on its thermal parameters as well as on different propagation mechanisms ...

Journal of Magnetism and Magnetic Materials, 2021
Abstract The magnetic-thermal-structural performances (MTSP) in an electromagnetic rail launcher have a significant influence on the successful launch capability. However, it is difficult to explore the MTSP directly through the experimental measurement due to the approximately adiabatic processes in the in-bore environment of the launcher, which ...

IEEE Transactions on Magnetics, 2000
A consistent iterative method for the simultaneous discretization of Maxwell's equations and of the heat conduction equation in weakly coupled systems is presented. The algorithm is an implementation of the finite integration method combined with both explicit and implicit FDTD schemes for the transient analysis.

The main goal is to present results of numerical simulations of induction heating process in pieces of cylindrical shape, using an inductor with variable step between the coils. Inducting heating process modelling was made with the Flux2D software and for study we present the temperature charts of the billet at different time steps.

2010 11th International Conference on Electronic Packaging Technology & High Density Packaging, 2010
As the information transmission medium widely used in the electronic equipment 3D interconnection, cables have many advantages, such as flexible routing, little electromagnetic interference, and highly cost effective, so they have an irreplaceable position for information transmission. In order to keep cables orderly and maintain easily, they are often
