摘要：
Resonant Bessel-beam launchers have recently gained much attention due to their capability to radiate focused beams by means of a compact and low-cost devices at microwave and/or millimeter waves. Most realizations consider only the use of TM-polarized beams, whereas only few works deal with the TE case. Here, we present an original workflow based on leaky wave theory for the design and performance analysis of both kinds of launchers in wireless power transfer (WPT) scenarios. Simple analytical formulas are provided and validated with both numerical and full-wave methods for different case studies. The results obtained here offer considerable insight into the WPT performance of such devices.
