Ultra-Wideband Antenna Characterization and Modeling
… of parameter modeling antenna systems using the Matrix-Pencil method has been demonstrated. It has been shown that it is possible to obtain frequency-domain patterns from pole/residue models of antenna realized effective length. Thus, a pole/residue model of the antenna realized effective length …

Design and Detection Process in Chipless RFID Systems Based on a Space-Time-Frequency Technique
… new time-frequency technique, called short-time matrix pencil method (STMPM), is introduced as an efficient approach for analyzing various scattering mechanisms in chipless RFID tags. By studying the performance of STMPM in early-time and late-time responses of the scatterers, the detection …

Analysis of an Embedded Singularity Chipless RFID Tag
The objective of this research is to explore the feasibility of a chipless RFID tag that stores a data signature in the form of complex frequency plane singularities. To this end an existing chipless RFID tag, the notched elliptical dipole tag, was analyzed first with simulations and then …

Noncommutative rational functions and their finite-dimensional representations
… skew field can be recovered from them. Firstly a matrix coefficient realization theory is developed, which for an arbitrary noncom-mutative rational function yields an efficiently computable normal form. Such a realization of a noncommutative rational function measures its complexity and describes its …

A Wide-Area Perspective on Power System Operation and Dynamics
Classically, wide-area synchronized power system monitoring has been an expensive task requiring significant investment in utility communications infrastructures for the service of relatively few costly sensors. The purpose of this research is to demonstrate the viability of power system monitoring …
