Wideband high-power transmission line pulse transformers
… kilovolt 100-picosecond pulses from a parallel plate geometry into a coaxial geometry, modeled after a transverse electromagnetic (TEM) cell. The transformer operates on a wide frequency bandwidth (.5-2 GHz) with minimal reflection or radiative loss (>1.5 dB loss across the frequency …

Effect of shear stress on surface membrane potassium ion permeability of calf pulmonary artery endothelial cells (Potassium ion)
… stress in the range 1-10 dynes/cm$\sp2$, in a parallel-plate geometry flow chamber, and the radioactivity of the effluent was monitored with time. Increase in laminar shear stress, from 1 dyne/cm$\sp2$ to a higher level, resulted in a rapid transient increase in the rate constant for $\rm …

The beam modes of general optical cavities
… by an application to two test cases, the parallel plate and Gaussian tapered mirror geometries. These two cases can be solved using methods other than the eigenvalue method. The parallel plate geometry is solved with the iterative solution to the integral equation and the Gaussian taper by …

Experimental investigation of electron multipactor discharges at very high frequency
… and investigates multipactor discharges in both parallel plate and coaxial geometries at very high frequency (VHF). CMX provides the first detailed investigation of multipactor energy distribution functions for both coaxial and parallel plate geometries with the use of retarding potential …

Studies of coaxial multipactor in the presence of a magnetic field
… multipactor discharges in the coaxial geometry in the presence of a constant and uniform magnetic field transverse to the direction of electromagnetic wave propagation. Studies on the Coaxial Multipactor Experiment (CMX) show that the magnetic field decreases the degree to which the …

Iterative Methods for the Reconstruction of Tomographic Images with Unconventional Source-detector Configurations
… device. The main challenge is the design of a geometry that optimally trades image quality for system size. The goal of this work has been to develop analysis tools to help simulate and evaluate novel system geometries. To test the tools we have developed, three geometries have been considered …

Studies on Functional and Rheological Characteristics of Hispanic Cheeses
… of these cheeses were determined by using a parallel-plate geometry viscoanalyzer.<br /> The results revealed significant differences (P There was a significant decrease (P In dynamic rheology spectra, elastic modulus (G') and viscous modulus (G") decreased during heating and increased during …

Influencing contact-line behavior in dynamic wetting through thermocapillarity and surface topography
… developing a Galerkin-finite-element model for a parallel-plate geometry motivated by the slot-die coating process, where it is found that generating a thermal Marangoni flow toward the contact line delays wetting failure to faster substrate speeds, which is crucial for increasing production rates …

Moisture and temperature effects on the dielectric spectrum of transformer insualtion materials
… of oil-free pressboard are measured using a parallel-plate geometry sensor for nine moisture levels and five temperature levels. A dielectric model for biological tissue is adopted here for cellulose structured pressboard. A universal curve is found relating dielectric properties to moisture …
