Generation of acoustic helical wavefronts using metasurfaces

Juan Ramon Mosig, Hervé Lissek, Seyyed Hussein Seyyed Esfahlani

It has been shown that acoustic waves with helical wavefronts can carry angular momentum, which can be transmitted towards a propagating medium. Such a wave field can be achieved by using a planar array of electroacoustic transducers, forming a given spati ...

Circularly Polarized Compact LTSA Array in SIW Technology

Juan Ramon Mosig, Marc Esquius Morote, Lei Wang

Typical linearly tapered slot antenna (LTSA) usually features a wideband and a high gain. However, its geometry size is large, especially very long in the tapering direction, which limits its application in compact antenna and array systems. This communica ...

Wideband H-plane dielectric horn antenna

Juan Ramon Mosig, Maria Garcia Vigueras, Lei Wang, Marcos Alvarez Folgueiras

By flaring a dielectric waveguide in the H-plane, an H-plane dielectric horn is formed, which could be directly excited by an SIW feed. However, matching and radiation performances are poor due to the thinness of the substrate. To improve these performance ...
