Anemia is a global health problem that affects both adults and children, but treatment is hampered by serious side effects, primarily associated with the gastrointestinal tract with oral administration of drugs. In this study, we aimed to develop an

In this paper, using a modified model of slowly varying amplitudes, a process of optics-to-THZ-conversion of vortex beams based on the nonlinear difference frequency generation in a medium with second-order susceptibility is considered. A theoretical

Design principles are proposed for a secure subterahertz RoF segment providing independent optical modulation by radiochannel frequency characteristics and a phased antenna array beamsteering parameter. A design scheme of the RoF segment for the W-ra

A schematic diagram of a RoF radio-optic system with vortex signals is presented, in which the radio frequency is determined by the difference between the wavelengths of two lasers. It is assumed that the generation of a vortex signal can be performe

In this paper, we consider the process of fiber vortex modes generation using chiral periodic structures that include both chiral optical fibers and chiral (vortex) fiber Bragg gratings (ChFBGs). A generalized theoretical model of the ChFBG is develo

Introduction: The transfer of image processing operations to the spectral region is considered. Due to the duality of information representation, coding, filtering, compression and other transformations are possible both in the space of an object and
