Near field interference of spoof surface plasmons propagating on two opposing faces of a thin metal sheet waveguide perforated by a periodic array of tapered holes has been investigated by time-domain terahertz spectroscopy. Closely spaced, chirped spectral interference fringes are observed in the output near the field as a result of the different nonlinear dispersion of the two surface modes. Results...
There has been a recent growth of activity in nonlinear time domain terahertz spectroscopy because of the development of a number of intense lab based sources and ultra-broadband detection schemes. Much of the interest stems from the possibility of exploring new physics by driving condensed matter far from equilibrium with THz fields in the 0.1 to 10MV/cm range [1]. The variety of different approaches...
