Information × Registration Number 0125U003282, ( 0226U000214  ) R & D request Title Formation of Bessel Non-Diffracting Beams in the Millimeter Wavelength Range Head Kuzmychov Ihor K., д.ф.-м.н. Registration Date 09-09-2025 Organization O. Ya. Usikov Institute for Radiophysics and Electronics NAS of Ukraine popup.description1 The aim of the research is to develop methods for forming Bessel non-diffracting beams in the millimeter-wave range using special lenses (axicons, fraxicons) and optimally designed apertures of conical antennas radiating axially symmetric modes of a circular waveguide. The creation of a working prototype within the atmospheric transparency window is planned for experimental verification of the proposed approach. popup.nrat_date 2025-09-09 Close
