Reconfigurable SIW-Based Leaky-Wave Antenna Composed of Longitudinal Cells
IEEE Access, 2021 A novel fixed frequency beam-steering leaky-wave antenna (LWA) is presented in this manuscript. Radiation occurs through thin offset longitudinal slots etched on a substrate integrated waveguide (SIW).

Microswitch beam-steering grid [PDF]
International Conference on Millimeter and Submillimeter Waves and Applications 1994, 2017 We propose new microswitch beam-steering grids to operate at 90 GHz and 240 GHz. The microswitch beam-steering grid has potential advantages over mechanical-scanning devices or active beam-steering reflectors based on diode grids such as lower loss and simple control circuits.

Optically Controlled Beam-steering Wireless Systems [PDF]
Optical Fiber Communication Conference (OFC) 2020, 2020 Wavelength-controlled 2D steering of mm-wave beams and infrared beams provides high communication capacity, privacy and energy efficiency. Using diffractive elements and accurate user localization, delivery of multiple 10GbE video streams by infrared beams is demonstrated.

Non-Mechanical Beam Steering with Polarization Gratings: A Review
Crystals, 2021 Polarization gratings (PGs) enable a novel architecture for dynamic non-mechanical steering of light over large angles and with large clear apertures. This beam steering approach has many applications in active sensing and optical communications. In this
