In this paper we combine the aperture field estimation technique and adiabatic Floquet-
wave expansion method for the analysis of leaky-wave holograms capable of generating …

Isotropic leaky-wave holograms have great potential in the synthesis of single-beam and
multibeam radiations in the desired directions. However, conventional methods are based …

The light diffraction on fork‐shaped binary phase holograms (BPHs) with quadratic
azimuthal phase term is considered. The distribution of intensity and phase, including …

The Laguerre-Gaussian beam is a typical example of the optical vortices, which can be
generated by computer-generated holograms (CGHs) with the topological charge controlled …

In this work we report experimental data confirming the analytically predicted transformation
of the topological charge (TC) of an input optical vortex (OV) beam, generated by means of …

A general orbital-angular-momentum (OAM) mode selection principle is put forward
involving the rotationally symmetric superposition of chiral states. This principle is not only …

In this paper, we demonstrate that the superposition of two vortex beams with controlled
topological charges can be realized by integrating two holographic plates with blazed …

High-resolution microwave leaky-wave holograms excited by a center-fed cylindrical-surface-
wave launcher show a null in the object-wave direction, which is an undesired effect for …

We report the first experimental generation of high-order Mathieu beams and confirm their
propagation invariance over a limited range. In our experiment we use a computer …

The properties and behaviour of electron beams possessing orbital angular momentum are
considered. Methods of their creation are discussed, but we concentrate mainly on the …
