Non-Contact Vital Signs Monitoring of Dog and Cat Using a UWB Radar
Animals, 2020 Simple Summary In this paper, we presented a new non-contact method to measure the vital signs of at-rest pets, where the ultra-wideband radar was applied for previously unachievable sensing ability and testing convenience.

Microwave detection of buried mines using non-contact, synthetic near-field focusing [PDF]
, 2001 Existing ground penetrating radars (GPR) are limited in their 3-D resolution. For the detection of buried land-mines, their performance is also seriously restricted by `clutter'. Previous work by the authors has concentrated on removing these limitations

Non-Contact Friction for Ion-Surface Interactions
, 2015 Non-contact friction forces are exerted on physical systems through dissipative processes, when the two systems are not in physical contact with each other, or, in quantum mechanical terms, when the overlap of their wave functions is negligible.

Adsorbate induced enhancement of electrostatic non-contact friction [PDF]
, 2005 We study the non-contact friction between an atomic force microscope tip and a metal substrate in the presence of bias voltage. The friction is due to energy losses in the sample created by the electromagnetic field from the oscillating charges induced ...
