A wire-to-plane discharge during the early phases of breakdown has been studied. The discharge has been modeled in a prolate spheroidal coordinate system with the wire shape taken as a hyperboloid of revolution. Four simultaneous coupled, time-dependent, nonlinear partial differential equations describe the electrical discharge. These are the conservation equations for ion and electron densitie...

Electromagnetic interference can be easily coupled into metallic shielding enclosure that is penetrated with a conducting wire, which having a harmful effect on electrical and electronic devices. To sudy the characteristics, Finite Difference Time Domain (FDTD) is applied in both frequency and time domain for modeling the coupling of an incident electromagnetic pulse (EMP) with a conducting wir...

Magnetic actuation has emerged as a useful tool for manipulating particles, droplets and biological samples in microfluidics. A planar coil is one of the suitable candidates for magnetic actuation and has the potential to be integrated in digital microfluidic devices. A simple model of microcoils is needed to optimize their use in actuation applications. This paper first develops an analytical ...
