According to the XRF spectral characteristics of heavy metals in soil,this paper analyzes the application of XRF spectra de-noising using biorthogonal wavel
Low-density parity-check (LDPC) codes combined with polarization scramblers are used to mitigate polarization mode dispersion (PMD) in 40 Gbit/s optical fib
In Microelectromechanical systems,the air thickness of a Fabry-Perot cavity is about one wavelength.Therefore,the interference series is less and the reflec
