Astronomers have discovered a giant, 500-light-year-wide cavity between two star-forming regions in the constellations ...

A cavity-backed antenna based on substrate-integrated suspended line (SISL) technology is proposed for 77 GHz applications. The antenna is designed to be self-packaged using six substrate layers with ...

In a digital age increasingly defined by speed, precision, and miniaturization, the world of photonics has found a rising ...

The Mamyshev oscillator (MO) is a type of fiber laser capable of producing high-energy laser pulses at a tunable repetition ...

Cavities form from tooth decay and can lead to pain or tooth loss. Here's a roundup of symptoms, causes and expert tips to protect your teeth and maintain good oral health.

In the early stages of plaque eroding or penetrating a tooth, cavities can be harder to spot. But more advanced ones will be easier to see as holes form on the surface of a tooth. Sometimes these ...

A broad range of coupon electropolishing experiments are described to ascertain the mechanism(s) by which large defects are formed near superconducting radio-frequency (SRF) cavity welds. Cold-worked ...

Benign tumors of the oral cavity are atypical formations of noncancerous cells that grow in the mouth. They can look like sores or lumps, and they typically develop slowly. Benign oral tumors are ...

This completed the assembly of the cavity, which could then trap light. The researchers had lots of control over the cavity-forming process, says Küçüköz.

Illustration of the core of the photonic cavity that was fabricated as two halves that assembled themselves into one unit. The cavity confines light inside the gap, which is only a few atoms wide as ...
