چکیده
A novel design method of simultaneous beam forming and focusing using a checkerboard anisotropic surface is proposed verified in this paper. The multibeam control regardless far near regions can easily be achieved through rearrangement the structure. unit cell utilized consists two identical metallic structures divided by dielectric material. When EM wave with circular polarization (CP) incident on cell, maximum transmission phase variation 360 degrees half rotation cell. microstrip patch antenna trimmed corners used to launch CP distance between about 2 wavelengths considering optimized spillover taper efficiencies. After designing each for focusing, cells are rearranged form checkerboard. feasibility confirmed full-wave simulation measurement angle 30 point 60 mm away from center at 5.8 GHz. focal length simulated measured 28 65 mm, respectively.

Thin anisotropic metasurfaces for simultaneous light focusing and polarization manipulation
The possibility of integration of two important categories of optical components, i.e., circular polarizer and lens, into a thin plasmonic metasurface is examined, for the realistic case when metal losses cannot be neglected, for example when operating in the visible spectrum, or at infrared when non-noble metals are used. We introduce a metasurface made of nanoantennas that offer enough degree...
متن کاملFocusing a helium atom beam using a quantum-reflection mirror
We demonstrate one-dimensional (1D) focusing of a thermal helium atom beam by quantum reflection from a cylindrical concave quartz mirror at near-grazing incidence. The smallest width of the focus achieved is 1.8μm, essentially limited by spherical aberration. The various effects that contribute to the finite focal width have been investigated. We propose to apply near-grazing reflection from t...

متن کاملAdaptive Digital Beam Forming using LMS Algorithm
There is a need of Phased Array Antennas in applications such as wireless communication, RADAR systems. The radiation pattern for this type of antenna has to be narrower sharper in one direction and should have nulls in other directions. In order to achieve this, phased array antennas are designed in such a way so as to steer the beam in required direction automatically. One of the techniques d...
متن کاملPrediction of Instability in Planar Anisotropic Sheet Metal Forming Processes
In this paper instability of planar anisotropic sheet metal during a few forming processes is investigated for the first time. For this reason components of the constitutive tangent tensor for planar anisotropic sheets are developed. By using the above tensor location of necking is predicted. Direction of the shear band is also predicted using the acoustic tensor. A finite element program is pr...
