Gallium arsenide is an attractive electronic device material because of its high electron mobility, high resistivity, high saturation velocity, low diffusivity and wide and direct energy bandgap. It has wide applications' in ...

The solid-state negative conductance devices such as Gunn's IMPATT's, etc. have proved to be potential sources of millimeter and microwave power. However, when singly operated these devices often fail to meet the power ...

The classical solution of electromagnetic wave inter action with penetrable bodies are limited to simple objects of separable boundaries such as spheres, cylinders etc. Recent developments in scattering of arbitrary ...

In data communication systems, the performance of the receiver is generally degraded due to the presence of the inter symbol interference (ISI) arising from the time-spread of the transmitted pulse. A linear transversal ...

The fast growing field of computers lays significant importance on the development of the CPU. This is more so for the design and development of single chip microcomputers. The present work is essentially concerned with ...

Petri nets (PN) have aroused considerable interest during the recent years as a model, primarily to represent and study concurrent systems. This thesis deals with the PN approach to design and development of modern ...

Biological processes are extremly complex, gene rally multivariable and nonlinear with complex patterns of control. This dissertation is a study of compartmen tal models of a large class of biological systems,where the ...

This work comprises a study of the influence of second harmonics on the output power and oscillation frequency of X-band waveguide Gunn oscillators. Only the resonant modes of operation of the Gunn diodes have been ...

The widespread application of paraboloidal reflector antennas in microwave communication, radar and radio astronomy has stimulated considerable interest in the development of physically small improved feed systems which ...
