This paper presents design of a defected ground structure coupled miniaturized dual-mode bandpass filter realized using a square patch. Two slots orthogonal to each other are cut on the patch to increase the path length of the fundamental mode while keeping the second mode current path almost unaffected. An inclined aperture cut on the ground plane right beneath the center of the patch is used ...

Aerodynamics of finite-span inclined square flat plates is experimentally investigated at a chord-based Reynolds number 50 000 in ground effect. The minimum height varied between gap ratios 0.1 to 1.0 chord lengths. All components forces and moments are measured using load cell for yaw angles 0° 180° an angle attack 30°. In addition, surface flow visualization planar, three-component particle i...

Two-dimensional numerical study of flow and temperature fields for laminar natural convection and radiation in the inclined cavity is performed in the present work. The walls of the square cavity are assumed kept at constant temperatures. An absorbing, emitting, and scattering gray medium is enclosed by the opaque and diffusely emitting walls. The set of governing equations, including conservat...

A numerical study is performed to analysis the buoyancy convection induced by the parallel heated baffles in an inclined square cavity. The two side walls of the cavity are maintained at a constant temperature. A uniformly thin heated plate is placed at the centre of the cavity. The horizontal top and bottom walls are adiabatic. Numerical solutions of governing equations are obtained using the ...

The crystal structure of the title compound has been determined. The coordination geometry about the iron(II) center is a tetrahedrally distorted square plane formed by the four-coordinate N2O2 donor set of the Schiff-base imine-phenol ligand. Molecules of the title compound are not planar. The two Schiff-base moieties, which themselves are reasonably planar, are inclined at an angle of 31.5(1)...
