Two-dimensional finite difference time domain (2D-FDTD) method is a very powerful electromagnetic numerical method for simulating electromagnetic(EM) problems of a complicated printed circuit board (PCB). However, due to the lack of transversal components of electric field intensities, it is hard to contain the coupling effect among isolated power/ground islands. In order to simulated the EM performance...
A full-wave analysis of the parasitic coupling effects between right-angle mitered bends microstrip discontinuities is presented. The full-wave analysis is performed by means of the spectral domain approach (SDA) which allows to include the effects caused by the surface and volume waves excited by the discontinuity. Using the computed field quantities, the scattering parameters of the structure are...
This paper demonstrates the feasibility of the wireless power transfer using dielectric coupling between a steel belt in a tire and a metal plate in a roadway. The scheme is called Tire Dielectric Coupling. We designed and prototyped the feeding subsystem using 1/32 scale models. The feeding subsystem is constructed of metal plates, tires and steel belts. We measured S-parameter of the feeding subsystem...
The importance of the sheath current wave such as Sommerfeld's single-wire wave (SSWW) increases in electromagnetic compatibility. In order to measure the reflection coefficient of SSWW equipment under test (EUT) (for example an absorbing clamp), we can use the slotted line method. But this method takes much time and more efforts, because the voltage or current distribution must be measured along...
