Metasurfing substrate integrated waveguides to mold the radiation from Leaky Waves

We show our latest developments in the application of the meta surfing concept to Substrate Integrated Waveguide (SIW) technology. It is described how this simple and versatile guiding medium can be conveniently modified and modulated to control the conversion from the conventional TE10 propagating mode to surface or leaky wave with tailored propagation and radiation features. Theoretical aspects and practical designs are described with the general objective of wavefront control (both in amplitude and phase), showing results at Ku band (12-18 GHz) and W band (75-111 GHz), and illustrating a wide range of physical phenomena and interesting potential applications.
