Transmission in a rectangular waveguide loaded with an arbitrary number of capacitive screens
Applied Scientific Research, Section B, 1958Green’s theorem is applied to individual domains consisting of the walls of a rectangular waveguide and two neighbouring slotted capacitive screens. In addition this theorem is applied to the two end domains, that is, the one containing the incident field and the other containing the transmitted field only.

Effect of screens on the turbulent flow in the quiescent zone of a rectangular aquaculture raceway
Aquacultural Engineering, 2013Abstract An acoustic Doppler velocimeter (ADV) was used to measure detailed vertical profiles of mean velocity and (for the first time) turbulence characteristics at the center of the quiescent zone (QZ) of operating aquaculture raceways. Instantaneous velocities were recorded at 10 Hz and averaged over a 360-s time interval in order to derive mean ...

Transmission Resonance Phenomena for a Narrow Rectangular Slot in Thick Conducting Screen
2018 Progress in Electromagnetics Research Symposium (PIERS-Toyama), 2018Two types of transmission resonance phenomena which are observed in a narrow rectangular slot structure in thick conducting screen is dealt with along with experimental verification. Some discussions are also given in connection with the transmission resonance phenomena occurring in the cylindrical hole structure in the real metal, which was once ...

Microwave absorption enhancement of rectangular activated carbon fibers screen composites
Composites Part B: Engineering, 2015Abstract The radar absorbing materials composited of activated carbon fibers (ACF) as wave-absorber and glass fibers (GF) as impedance modifier were successfully prepared. The structure parameters of rectangular ACF felt screen, the influences of GF-piece and the reflection properties were investigated.

Efficient MLFMA analysis of coupled rectangular and circular apertures in a finite screen
IEEE MTT-S International Microwave Symposium Digest, 2003, 2003A multilevel fast multipole algorithm (MLFMA) is introduced for the efficient analysis of coupled rectangular and circular apertures of different size within a finite conducting screen. The electric field integral equation (EFIE) is written in terms of mixed potential formulation.

Plane wave diffraction by a small rectangular aperture in a thick conducting screen
2016 International Conference on Electromagnetics in Advanced Applications (ICEAA), 2016Based on the application of the exact solution for the plane wave diffraction by a rectangular hole, the transmission property of a rectangular aperture less than the half-wavelength is investigated by calculating the transmitted power for various aperture sizes and screen's thicknesses, and we derive a useful formula for predicting the transmitted ...
