Zero effects field in electrodynamic experimental observations

At a research in free space of angular and frequency dependences of the reflected wave on a dielectric plate areas of abnormal attenuation of amplitude and, at the same time, change of a phase on π which are called areas of zero effects under certain conditions are observed. There is a question of a possibility of observation of similar effects in other areas of radio engineering. Purpose of article – experimental confirmation of emergence of conditions of emergence of areas of zero effects in the field of the waveguide equipment.

It is considered emergence of zero effects in the waveguide equipment and experimental measurements of frequency dependences of amplitudes and phases of coefficients of reflection and transfer from the waveguide resonator with the entered dielectric core are presented. It is shown that use for control of depth of introduction of a dielectric core with high dielectric permeability in the resonator, allows to receive abnormally high absorption of coefficients of reflection and transfer of the waveguide resonator.

Practical importance. As a result of the taken experimental measurements the waveguide design of the volume resonator with the entered dielectric core with high dielectric permeability which can be used as a separate waveguide element when designing measuring systems, in particular, the rejection of filters is found.
