The paper considers the waveforms of signals received in the sidelobe region of an antenna, when the signals are of very short duration. It is shown that the output signal waveforms can be very different from those of the input signal. An analysis is

From measurements of transmission through thin sheets and reflection from them, at oblique incidence, both the real and imaginary components of permittivity and permeability of a material can be determined. Except for the generator, antenna and detec

The plane wave spectrum analysis is extended to the study of three-dimensional Gaussian beam propagation and scattering. The reflection of a three-dimensional circular Gaussian beam from a parallel-sided ferrite slab, backed by a ground plane, is the

A new free-wave method for measuring complex permittivity and permeability of materials at mm-wave frequencies is introduced. The use of time gating for removing the unwanted reflections within the sample, and its advantages in simplifying the calcul

The novel concept of microwave forceps is introduced, and some of the authors' preliminary findings presented. The authors feel that it is far too early to claim that this approach to sealing blood vessels will be ultimately successful, but they thin

The theory of the open resonator is now established, at least so far as scalar wave functions are adequate to describe the field distribution. In this treatment we shall pay particular attention to the rather subtle modifications to the theory that a

A method of measurement of antenna radiation patterns is described. The variations in reflection coefficient at the antenna feed were recorded as a thin wire is moved past the antenna aperture. It is shown that for antennas whose aperture distributio
