Multi-access broadcast channels (such as ETHERNET or Fasnet [5], [6]) have the feature that a message is broadcast to all users, so that only one user can transmit on the channel at a time. The utilization of such a channel would be increased if it were possible for more than one user to occupy the channel at the same time. We consider the performance of a hypothetical channel having the proper...

Abstract We demonstrate engineering of the low-terahertz range plasmonic spectra two-dimensional electron systems by modifying their geometry. Specifically, we have modelled, fabricated, and measured two devices for comparison. The first device has a rectangular channel, while second is trapezoidal, designed to support richer spectrum causing variation in width along direction plasmon propagati...

To perform specific analysis for the single cell, individual cells have to be captured and separated from each other before further treatments and analysis can be carried out. This paper presents the design, simulation, fabrication, and testing of a microfluidic device for trapping a single cell/particle based on a hydrodynamic technique. A T-channel trapping chip has been proposed to provide s...

We adress the question of the stability of a confined coflowing jet at low Reynolds number in various geometries. Our study is motivated by recent experiments in microfluidic devices. When immiscible fluids flow in microchannels, either monodisperse droplets or parallel flows are obtained depending upon the flow rate of the aqueous phase and the oil phase. In these experiments, the confining an...

We address MIMO systems in the presence of frequency selective fading. We first describe our channel model, then we derive capacity formula, and finally we develop a linear coding procedure for the obtained channel model. Starting from a physical mobile channel model with known scatterer geometry, we develop a MIMO FIR channel model. Our channel model results in stationary, ergodic vector proce...

In this paper, an analytical modeling is presentated to describe the channel noise in GME SGT/CGT MOSFET, based on explicit functions of MOSFETs geometry and biasing conditions for all channel length down to deep submicron and is verified with the experimental data. Results shows the impact of various parameters such as gate bias, drain bias, channel length ,device diameter and gate material wo...

This paper presents a low-complexity algorithm for the simulation of time-variant frequency-selective geometry based channel models. The algorithm approximately calculates the time-variant transfer function of the channel in the subspace spanned by multidimensional discrete prolate spheroidal (DPS) sequences. The only parameters of the subspace are the maximum Doppler shift and the maximum dela...
