We consider here how to build a balun for f%st-nsetime pulses at high vokage. We are concerned with signals with risetimes on the order of 100-200 ps, with high peak voItages and peak powers. We propose the simplest method is a coaxial unzipper. We consider dielectric strength and maximum coaxial radius allowable while still maintaining the risetime. Also considered are methods to reduce the co...

The contribution of ions to the electrical impedance of an electrolytic cell limited by perfect blocking electrodes is determined by considering the role of the anomalous diffusion process and memory effects. Analytical solutions for fractional diffusion equations together with Poisson's equation relating the effective electric field to the net charge density are found. This procedure allows th...

In this paper the current distribution is calculated for a microstrip line in the presence of a neighboring strip. The electric field is calculated and the characteristic impedance of the slotted ndcrostrip line is determined. A graph of characteristic impedance is given for odd and even excitations. The calculations are carried out by setting up a singular integral equation which is solved usi...

The general objective of this research is to extend our knowledge of the properties of electric networks, active or passive, reciprocal or nonreciprocal, linear or nonlinear. The topics that are being investigated are: (a) circuit models of linear nonreciprocal networks; (b) topological methods of analysis for linear nonreciprocal networks; (c) properties of RC networks that contain dynamically...

Microfluidicsand nanofluidics-based impedance sensors play an important role in identification of toxic industrial chemicals and pathogens in biodetection and biodefense arena. However, their efficient modeling and design continues to be a challenge. This paper presents high-fidelity models to resolve the electrokinetic transport process at the microand nano-scale and capture the critical effec...

An analytic model is proposed to estimate the electromagnetic field transmission line coupling for both radiated emission and immunity using TEM cell measurements. Further, a coupling impedance is introduced to determine the domination between electric and magnetic fields of the fieldline coupling. Comparison of measurement and calculation results confirms the accuracy of the model. The model a...
