A perfect electromagnetic conductor (PEMC) sphere illuminated by linearly-polarized plane
progressive waves is known to experience a positive/repulsive force regardless of the …

The scalar complex source vortex model is an accurate description of highly focused scalar
vortices. We use it to construct a variety of vectorial solutions of Maxwell's equations …

This textbook is aimed at university students specializing in mathematics and natural
sciences and at all the readers interested in studying complex analysis. The mathematical …

We discuss the generation and propagation of nondiffracting twisted pulses at microwaves,
obtained through polychromatic spectral superposition of higher-order Bessel beams. The …

Spherical waves in which one of the coordinates of a source point is complexified are
considered. Interest in such exact solutions of the wave equation known as “complex source …

A new type of exact solutions of the full 3 dimensional spatial Helmholtz equation for the
case of non-paraxial Gaussian beams is presented here. We consider appropriate …

Exact Hermite-Gaussian solutions to the Klein-Gordon equation for particle beams are
obtained here that depend on the 4-position of the beam waist. These are Bateman-Hillion …

Neurological pathologies, especially optical neuro-pathologies, can be studied by means of
OCT (optical coherence tomography). Tomography generally allows to investigate inner …

Bessel-beam launchers are promising and established technologies for focusing
applications at microwaves. Their use in time-domain leads to the definition of a new class of …
