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 ...

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 ...

Aortic pressure wave reflection is one of the risk factors for developing cardiovascular disease in adults, and the degree of pressure wave reflection increases with aging. However, enhanced pressure ...

Considering that arterial stiffness and subsequent increases in wave reflection precede hypertension, 15, 16 it is plausible that the effect of wave reflection on early stages of LV diastolic ...

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 ...

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 ...

Physicists in the US have observed an effect known as time reflection in an electromagnetic wave for the first time. They detected the phenomenon – the temporal counterpart of familiar spatial ...

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 ...
