Mechanical antennas represent a disruptive approach to low-frequency communication by exploiting the mechanical oscillation of electric charges or magnetic dipoles to generate electromagnetic ...

Raman spectroscopy is an analytical technique that allows for the assessment of molecular structure and the identification of materials by examining the rotational and vibrational modes of molecules.

A team of physicists has developed a method to detect gravity waves with such low frequencies that they could unlock the secrets behind the early phases of mergers between supermassive black holes, ...

A metamaterial elongates the propagation path of sound waves, allowing low-frequency noise control without the need for bulky materials.

Research conducted by a team of scientists from Kaunas universities, Lithuania, revealed that low-frequency ultrasound influences blood parameters. The findings suggest that ultrasound’s effect on ...

We all know how to block the DC offset of an AC signal — that just requires putting a capacitor in series, right? But what if the AC signal doesn’t alternate very often? In that case, things get a ...

Acoustic frequency combs organize sound or mechanical vibrations into a series of evenly spaced frequencies, much like the teeth on a comb. They are the acoustic counterparts of optical frequency ...

Research conducted by a team of scientists from Kaunas University, Lithuania, revealed that low-frequency ultrasound influences blood parameters. The findings suggest that ultrasound's effect on ...

Most oscilloscopes are fitted with filters to help improve measurement by reducing overall noise in an acquisition to improve signal-to-noise ratio (SNR). Even the most basic oscilloscopes include an ...
