Abstract
Section titled āAbstractāThe types of light fields that can be generated with the use of proposed by the authors 4-channel modulator (LC focusing device) in different modes depending on the value of <i>Ļl</i> (where <i>Ļ</i> is the modal parameter,<i> l</i> - the characteristic size of the aperture and the square of <i>Ļl</i> is the ratio of the resistance of the high resistance layer and the impedance of the LC layer) are analyzed. By means of numerical simulation it was shown that <i>Ļl</i> value determines reshaping of equipotential lines of voltage from ring/ellipses to square/parallelogram contours or octagon contours. The capability of LC focusing device to generate light fields with intensity distribution in the shape of intersections, sets of points, boundaries of squares, diamonds, parallelograms, octagons is demonstrated. Obtained light fields can be useful in the problems of optical manipulation.
