Coupled mode theory has recently been applied to study finlines loaded inhomogeneously with a dielectric or a ferrite. The authors report the results of the application of the coupled mode theory to obtain the propagation ...

The effects of a scattering medium on the performance of time-delay estimation are considered. The medium is assumed to exhibit angular scattering, causing angular (as well as delay) dispersion and hence loss of signal ...

In this note, the design technique given by Sebakhy and Sorial [1], based on both pole placement and optimal control, is extended to obtain a sensitivity reduced optimal linear regulator with prescribed closed-loop ...

The paper describes a method for implementing direct-digital-control (DDC) algorithms on readily available microcomputers using distributed arithmetic. With the use of distributed arithmetic, fast execution of the control ...

A structure to realize a first-order two-dimensional all-pass transfer function with five multipliers and two delays has been proposed. This has been achieved by modifying the signal flowgraph of an existing structure which ...

When a phased array is used in a large bandwidth system, such as a pulse-compression system, significant distortions can arise [1]-[4]. Apart from depending on array system parameters, such as aperture length, type of feed, ...

A geometric formulation of the "null-steering" array antenna pattern synthesis problems for arbitrary array geometries is proposed. The formulation allows the use of some simple intuitive techniques for the construction ...

Synthesis of array patterns involving optimization with linear and nonlinear constraints is considered. The general solution for the composite weight vector can be decomposed into a part which satisfies the linear constraints ...

This correspondence is addressed to the question of invertibility of linear dynamical systems. Specifically, inversion over principal ideal domains is discussed in view of the fact that 2-D systems can be considered as 1-D ...
