To evaluate whether natural attenuation can achieve legal standards for groundwater cleanup, the fate of contaminants in the groundwater environment has to be well understood. In what direction do the ...

A depth-compensated diffractive optical element photoacoustic microscope enables more uniform photoacoustic imaging across tissue depths.

Pressure waves propagating through bubble-containing liquids in tubes experience considerable attenuation. Researchers at the University of Tsukuba have derived an equation describing this phenomenon, ...

As seismic waves travel through Earth, they gradually lose energy, a process called attenuation. That energy loss doesn't happen uniformly—some features in the crust sap far more energy from seismic ...

Measuring attenuation in a fiber-optic cable is a vital ingredient to obtaining the maximum performance from a system designs. But, for designers, just starting to work in the fiber-optic design space ...

This rule of thumb enables us to estimate how much attenuation would be in the loss budget of a serial channel. Spoiler summary:With no equalization, about -10 dB at the Nyquist. With just CTLE, about ...

Documenting that a contaminant has disappeared or that the concentration has become very low in groundwater samples is an important piece of information for proving that natural attenuation is working ...
