It is difficult to select an optimal atmospheric dry refractivity profile model from the existing models for practical applications. As the atmospheric wet refractivity profile model has a lower precision, the demand to construct an improved model of...

Abstract:
Performance of electric contact between armature and rails（A-R） developed as armature sliding in railgun bore, in which electromagnetic(EM) characteristics at A-R interface was the fundamental mechanism. Based on transient magnetic field calculation ...

Abstract:
The problem of calculating electromagnetic quantities of the circuit in the complex cavity is studied in this thesis. A wave chaotic cavity is built, and its radiation and scattering parameters are obtained by testing. Based on RCM, the electromagnet...
