The design and metrological applications of Fabry-Perot resonators in the microwave and
millimetre regions of the electromagnetic spectrum are reviewed. The review opens with …

In this paper we describe a new method of using pulsed Fourier transform microwave
spectroscopy to observe transient or otherwise shortlived species. Previously, we have …

A method for the measurement of permittivity at microwave frequencies using an open
resonator is proposed. The theory of the method is developed, and an experimental …

Using the complex source-point method, we deduce simple approximate formulae for the six
rectangular components of the electromagnetic field of a Gaussian beam. It is shown that in …

Nondestructive, contactless, and label-free characterization of small particles plays an
important role in laboratory research and industrial manufacturing. Also, the analysis of …

This article proposes a novel measurement method based on parallel-plate dielectric
resonator (PPDR) for determining complex permittivity of low-loss dielectric materials over a …

Following a brief survey of the theory of Laguerre-Gaussian beam modes, expressions are
derived for the paraxial vector electric and magnetic fields for wave modes of arbitrary order …

A detailed study by theory, simulation, and measurement is presented for electromagnetic
scattering from alumina ceramic spheres covering a frequency range from 50 to 220 GHz …

We propose a modified split-cylinder resonator (SCR) with open slits, which can suppress
the majority of TM modes while lowering the quality factors of nonzero azimuthal mode TE …
