A new self-powered water sensor uses wave energy to monitor pollutants like heavy metals, microplastics, and pesticides—no ...

Abstract: A new method based on application of millimeter waves for measurement of complex refractive index of thin semiconductor films on high resistive substrates is described. Published in: 2004 ...

Numerical results for attenuation of centimeter waves by rainfall have been computed from J. W. Ryde's formula. These correct, and considerably extend, the previously published Ryde results.
