Abstract: Due to power attenuation, improving transmission efficiency in the radio-frequency (RF) band remains a significant ... To address this issue, we propose the RF-based resonant beam system (RF ...

Here, we show that microwave near-field sensing using a high-sensitivity resonant coaxial transmission line probe can be used to monitor the evaporation rate of both liquid droplet and liquid level.

Anybody can develop high frequency hearing loss, but it becomes more common with age. Exposure to loud sounds or high frequency sounds are common causes of ear damage in younger people.
