A basic mechanical phase-shifter is described and proposed for use as a reference circuit for impedance measurements with a phase modulation method. It consists of a section of a curved rectangular waveguide, the length of which is mechanically varie

The authors present a resonant permittivity measurement method which works over a large microwave frequency domain, with a very small volume sample of dielectric material. The cell is a helical resonator having many modes of resonance. The shifts of

A helical RF industrial applicator was evaluated for heating minced meat flowing in a hollow tube. Heating was homogeneous inside the product, although the product was highly lossy due to its high electric conductivity. The homogeneity was much bette

A system for measuring the amplitude and phase of three components of the electric field vector at 2450 MHz is described. It uses three optically modulated phototransistors which disturb only weakly the electric field distribution. The authors also p

Reduction of nitrogen oxides under oxidative atmosphere is a very extensively studied reaction, but it is still very difficult to understand and to follow the various pathways of the reaction. Two alumina supported 0.2 wt% platinum catalysts, reduced

An apparatus is described for studying industrial RF assisted processes, on the laboratory scale. The applied electromagnetic field can be as intense as that used in industry; it can be varied for performing step changes, constant temperature, or con

The effects of microwave irradiation of an alumina-supported 0.2 wt.% platinum catalyst are studied. In the case of the isomerization of hexanes, the selectivity in isomers is increased (by a factor 1.3 to 2) when the thermal treatment of the catalys

The authors discuss some methods of permittivity and permeability measurements which use a single rectangular sample of material placed in a waveguide. They discuss the accuracy to which the vector network analyzer (VNA) is calibrated, and if the lea
