Abstract: A compact flat-bottom Luneburg lens antenna with 2-D beam scanning capability is developed and implemented using 3-D printing techniques based on the transformation optics (TO) method. A ...
Applied physicists in the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) have demonstrated a new way to structure light in custom, repeatable, three-dimensional patterns, ...
Optical photothermal infrared (O-PTIR) spectroscopy is an infrared super-resolution measurement technique where a shorter ...
Time is almost up on the way we track each second of the day, with optical atomic clocks set to redefine the way the world ...
Abstract: The terahertz (THz) band is critical for 6G systems, yet high-gain circularly polarized (CP) antennas remain challenging due to fabrication and performance constraints. This work presents a ...
