Establishment of signal integrity over a broad band as well as suppression of electromagnetic coupling between wirings in ICs are significant problem, because packaging density in ICs is very high. To clarify the electromagnetic compatibility (EMC) problems that related to the interconnection in the IC chip, transmission characteristics and electromagnetic coupling between wirings in the specia...

We reevaluate the hadronic part of the electromagnetic vacuum expectation value using the standard dispersion integral approach that utilizes the hadronic cross section measured in e + e − experiments as input. Previous analyses are based upon point-by-point trapezoidal integration which does not treat experimental errors in an optimal way. We use a technique that weights the experimental input...

A new type of permanent magnet actuator driven by electromagnetic repulsive force in breaking course and electromagnetic attraction force during closing course is presented in this paper, and the static and dynamic characteristics for contactor with this new type actuator are mainly focused on by simulation and experiment simultaneously. Firstly, the static electromagnetic attraction force in c...
