Near-Field Links with Obstructed Line of Sight via Bessel Beams

Résumé

The generation and propagation of Bessel beams between two apertures with obstructed line-of-sight at microwave frequencies is studied herein. Both the transmitting and receiving apertures are based on leaky radial waveguides consisting of an array of metallic patches over a grounded dielectric substrate. The present work focuses in the case where an axially aligned metallic obstacle is placed between the two launchers to validate the self-healing feature of Bessel beams. Obstacles with different radius are considered and their effect in the power efficiency studied. A limit for the radius' scatterer is defined up to which the self-healing property of the generated Bessel beam is valid.
