A design of a linear array antenna having two radiation nulls and otherwise omnidirectional
radiation pattern is reported. A new configuration of a waveguide broad wall longitudinal slot …

A longitudinal slot at the centre of the broad wall of a rectangular waveguide in the presence
of one or two vertical strips has been analysed. The combination is excited by the dominant …

An important area of application of high-power radio frequency (RF) and microwave sources
is particle acceleration. A major challenge for the current worldwide research and …

A suitable method is introduced to excite the centreline longitudinal slot antennas. For each
slot, an iris and a rectangular septum are employed at the opposite sides of the slot such that …

Admittance characteristics of a rectangular radiating slot in the broad wall of a rectangular
waveguide are evaluated by the method of moments, using a conventional approach for free …

This is a study of the indigenous people of the Hudson Bay Lowlands, known as the
Lowland Cree. The time period is coincident with the European fur trade period in the region …

ABSTR. ACT A general formulation for the scattering from multiple discontinuities in
waveguides is presented in this thesis. The global scattering matrices are derived from the …
