A tailor-made structure may make microwave WiFi signals more transmittable through walls without reflection, according to new research. This works in much the same way as anti-reflective coating on a ...

The effects of solar activity on the stratospheric waveguides and downward reflection of planetary waves during NH early to midwinter are examined. Under high solar (HS) conditions, enhanced westerly ...

DURHAM, N.C. -- Researchers at Duke University and Aalto University (Finland) have constructed a "meta-mirror" device capable of perfectly reflecting sound waves in any direction. The ...

Owing to the wave nature of light there are many ways that such different waves can interact with each other, but also with materials. Everyone knows about reflecting light with a mirror, which is a ...

Compared to general metal reflectors, the new product is capable of reflecting millimetre waves in a more targeted manner. As a result, there are fewer restrictions on installation, making it possible ...

Researchers have constructed a 'meta-mirror' device capable of perfectly reflecting sound waves in any direction. The proof-of-principle demonstration is analogous to looking directly into a mirror ...
