This letter proposes a novel antipodal Vivaldi antenna with characteristics of ultra-wideband and high gain with stable radiation pattern. To further enhance the working bandwidth from a traditional ...

This letter presents a new low-profile, reconfigurable pattern antenna. The antenna features a printed circular segmented loop fed by two separate feed points coupled to a parasitic composite ...

Southwest Research Institute (SwRI) is expanding its antenna measurement capabilities with a state-of-the-art spherical ...

Quasi-isotropic antennas are designed to deliver uniform radiation in almost all directions, thereby ensuring optimal signal coverage in complex communication environments.

Radiation damage remains the principal limitation in achieving higher resolution in cryo-electron microscopy (cryo-EM), ...

Since the discovery of planetary nebulae in the late 1700s, astronomers have learned that these expanding shells of glowing ...

To prevent cheating, the West Bengal Higher Secondary Council will implement an S-shaped seating arrangement for the upcoming semester-based Higher Secondary examination starting September 8th ...

After testing some 115 lights over the past 10 years, we can recommend the best headlight and the best taillight for most people who commute by bicycle.
