Broadband ultrasonic imaging shows defects in all types of concrete
Concrete structures like roads and bridges require nondestructive testing methods to identify interior defects without destroying their structure. Most methods send sound waves into the material and ...
In the ETH experiment, self-oscillations (blue-red) cause sound waves (green, orange, violet) to travel through the circulator only in one direction. Credit: Xin Zou Researchers at ETH Zurich have ...
Scientists in Finland transmitted electricity through air using sound waves, lasers, and radio frequencies, creating ...
The terahertz quantum cascade laser on its mounting. Credit: University of Leeds Lasers that switch on and off billions of times per second are the backbone of optical communications networks, but ...
Researchers have revealed how high-frequency sound waves can be used to build new materials, make smart nanoparticles and even deliver drugs to the lungs for painless, needle-free vaccinations. While ...
