A novel fixed-frequency electronically-steerable one-dimensional (1-D) leaky-wave antenna
is presented. The antenna is based on a parallel-plate waveguide loaded with a planar …

For many leaky-wave antennas (LWAs), it is challenging to realize beam scanning through
broadside. A problem is the presence of an open stopband (OSB), which restricts radiation …

We report on an innovative reconfigurable antenna concept with significant practical
relevance based on the dynamic definition of metal-like conductive plasma channels in high …

An electrically controlled beam-scanning circularly polarized leaky-wave antenna is
presented by cascading multiple unit cells of a composite right/left-handed transmission line …

We report an electronically switchable dielectric leaky wave antenna. The main beam angle
can be electronically steered using pin diodes. The diodes are used as switches to control …

We report a 0.74-THz beam-steering and forming antenna based on dynamically
reconfigurable photo-induced Fresnel zone plates (PI-FZPs) formed by patterned …

The term space wave refers to a wave that is propagating through an open medium with a
diverging wavefront as it moves away from the source. The term guided wave denotes a …

Beam-steering millimeter-wave (MMW) antennas using photo-induced plasma gratings
(PIPGs) offer a dramatic decrease in fabrication cost compared to their phased-array …

Directive optical leaky wave antennas (OLWAs) fabricated in CMOS-compatible
semiconductor planar waveguide technology have the potential to provide high directivity …

Nous présentons dans ce papier trois exemples de travaux menés à Toulouse par des
équipes issues des communautés micro-ondes et plasma. L'objectif est d'utiliser des …
