  • Gas Sensing using Terahertz Time-Domain Spectroscopy 

    Mittleman, Daniel M.; Jacobsen, R. H.; Neelamani, Ramesh; Baraniuk, Richard G.; Nuss, Martin C. (1998-01-15)
    A method for detection and identification of polar gases and gas mixtures based on the technique of terahertz time-domain spectroscopy is presented. This relatively new technology promises to be the first portable far-infared ...
  • Optimal wavelets for signal decomposition and the existence of scale limited signals 

    Odegard, Jan E.; Gopinath, Ramesh A.; Burrus, C. Sidney (1992-05-20)
    Wavelet methods give a flexible alternative to Fourier methods in non-stationary signal analysis. The concept of <i>band-limitedness</i> plays a fundamental role in Fourier analysis. Since wavelet theory replaces ...
