AN OPEN RESONATOR LOADED WITH A RECTANGULAR WAVEGUIDE SECTION
Radio Physics and Radio Astronomy, 2014 A hemispherical open resonator with a rectangular waveguide section mounted at the center of the open resonator plane mirror is considered. A theoretical analysis has been made to find out that the excitation efficiency of the waveguide wave TE10 excited

Power Summation in an Open Resonator with Aperture Coupling Elements
Advanced ElectromagneticsThe paper considers the powers summation of two sources in a hemispherical open resonator (OR). A scheme with a E- tee waveguide was used. The study was carried out in the four-millimeter wavelength range.

Open Resonator System for Reflectarray Elements Characterization [PDF]
International Journal of Antennas and Propagation, 2012 An open resonator system is proposed in this work to study the phase behavior of reflectarrays cells. The characterization of the single reflectarray element is performed by assuming a Gaussian plane wave normally incident on an infinite periodic array ...

Design of a Dual-Band Bandpass Filter Using an Open-Loop Resonator [PDF]
Journal of the Korean Institute of Electromagnetic Engineering and Science, 2017 In this paper, we present a novel design for a dual-band bandpass filter (BPF) based on the conventional second-order, open-loop BPF. By adding series resonant circuits to the open ends of the resonator, we can create two resonant modes from the even and

Dynamics of Alfvén waves in the night-side ionospheric Alfvén resonator at mid-latitudes [PDF]
, 2005 International audienceA numerical solution of the problem on dynamics of shear-mode Alfvén waves in the ionospheric Alfvén resonator (IAR) region at middle latitudes at nighttime is presented for a case when a source emits a single pulse of duration ...
