This paper represents the evaluation of capacitance of different conducting bodies are calculated using finite element method (FEM). There are different numerical methods like Finite Difference method, Method of Moment and Monte Carlo methods. But the finite element method has more advantages. The surfaces are discretized using triangular subsections. Finite element method is a suitable method ...

A new reflecting surface capable of simulating identical reflecting properties of a metallic plate with rectangular corrugations is reported. The new surface which is fabricated with a low loss dielectric plate of uniform thickness .One surface of the plate is periodically loaded with a grill structure of conducting wires and the other surface is completely metalized with copper. Depending on t...

This paper shows experimental results of packet error rates (PERs) in wireless-LAN mounted printed circuit boards and gives a discussion on a mechanism of electromagnetic noise coupling that affects the PER. We utilized the amplitude probability distribution (APD) to investigate the noise coupling channel. We measured magnetic near-field distribution to obtain information about a noise source. ...

In this paper, the electromagnetic properties of two different High Impedance Surfaces (HIS) with or without Electromagnetic Band Gap (EBG) in different configurations are investigated for mutual coupling reduction in small antenna arrays. The resonant mechanisms of these structures are studied using transmission calculations in a parallel plate waveguide. An optimum configuration is then propo...

Electromagnetic waves propagating in air are visually observed with phase evolution in real time by live electro-optic imaging technique. We show how geometrical and crystallographic arrangements of an electro-optic sensor plate enable the realization of the real-time visual observation of traveling 100-GHz electromagnetic waves. For this purpose, a generation technique for a 100-GHz optical lo...

Analytic calculations of the electric field of a parallel-plate capacitor are notoriously difficult [1, 2, 3, 4, 5, 6, 7, 8]. The usual goal of such efforts is a calculation of the correction to the hard-edge approximation, C = A/4πd (in Gaussian units), of the capacitance for plates of area A separated by distance d. Calculate instead the electromagnetic momentum of the parallel-plate capacito...
