Reconfigurable Curved Beams at Terahertz Frequencies Using Inverse-Designed Bilayer Diffractive Structures
Wei Jia, Miguel Gomez, Steve Blair +1
Curved electromagnetic beams at terahertz (THz) frequencies have recently emerged as a powerful example of wavefront engineering, with applications in imaging and high-capacity wir…
Holographic Mapping of Orbital Angular Momentum Using a Terahertz Diffractive Optical Neural Network
Wei Jia, Miguel Gomez, Steve Blair +1
Using orbital angular momentum (OAM) in the terahertz (THz) range provides a new degree of freedom for communication and imaging systems. This study presents a compact diffractive…
Control of Extraordinary Optical Transmission in Resonant Terahertz Gratings via Lateral Depletion in an AlGaN-GaN Heterostructure
Geofrey Nyabere, Hunter Ellis, Miguel Gomez +7
Periodic metallic gratings on substrates can support a range of electromagnetic modes, such as leaky waveguide, guided-resonant, and Fabry-Perot (FP) cavity modes, which can strong…
Degradation of 2.4-kV Schottky Barrier Diode at High Temperatures up to 500 °C
Hunter Ellis, Wei Jia, Imteaz Rahaman +5
Ga2O3 Schottky barrier diodes featuring a field plate and a composite SiO2/SiNx dielectric layer beneath the field plate were fabricated, achieving a breakdown voltage of 2.4 kV at…
