Direct observation of polarization distribution at nanoscale by scanning force microscopy across partially etched Pb(Zr,Ti)O-3 film ferroelectric capacitors with size 2x3 mum and preferential orientation (111) has revealed an anomalous polarization pattern ...
This paper presents a preliminary work on a resonant circuit, also called AC-dipole. The resonance frequency of the circuit is changed by the mean of a variable capacitor connecting an inductor. For this purpose, a bank of switched capacitors of different ...

Stress-induced changes in the imprint and switching behavior of (111)-oriented Pb(Zr,Ti)O-3 (PZT)-based capacitors have been studied using piezoresponse force microscopy. Visualization of polarization distribution and d(33)-loop measurements in individual ...
Accurate modeling and efficient parameter extraction of a small signal equivalent circuit of MOS transistors for high-frequency operation are presented. The small-signal equivalent circuit is based on the quasi-static approximation which was found to be ad ...
In this work, a model of a multi-layer high-Tc superconducting (HTS) cable that computes the current distribution across layers as well as the AC loss is presented. Analyzed is the case of a four-layer cable, but the developed method can be applied to a ca ...
Distributing power and ground to a vertically integrated system is a complex and difficult task. Interplane communication and power delivery are achieved by through silicon vias (TSVs) in most of the manufacturing techniques for three-dimensional (3-D) cir ...

This paper introduces a special mx3 matrix converter connected between the stator of a poly-phased synchronous generator and a power grid. Some commutations of the chosen switching scheme induce voltage surges due to leakage inductances of the generator. T ...

Equivalent circuits based on the telegrapher's equations are suited for calculation of transient phenomena in transmission lines in the time domain. In order to simulate the frequency dependent properties of real lines, one-port networks are included in th ...
A method to extract a lumped-parameter equivalent circuit for a free-free flexural MEMS resonator, based on the Euler-Bernoulli beam equation and exploiting a modal analysis approach, is presented. The dynamic behaviour predicted by the equivalent circuit ...
A new, compact way to match slot antennas to a coplanar waveguide (CPW) feed is presented. In addition to its advantages of flexibility, reduced size, and increased bandwidth, a good analytical approximation of the matched antenna behavior is possible. An ...
