Leaky-Wave Synthesis of Bessel Beams at Millimeter-Wave Frequencies

Bessel beams are focusing shaped beams that have recently attracted much interest for several practical applications thanks to their limited-diffracting and self-healing properties. Bessel-beam launchers are planar devices capable of generating Bessel beams. In this contribution, we show how to effectively model and design various types of such devices working at millimeter waves through a straightforward, accurate, and rigorous leaky-wave approach.
