The electromagnetics of light transmission through subwavelength slits in metallic films
(OPTICAL SOC AMER, 2011)
By numerically calculating the relevant electromagnetic fields and charge current densities, we show how local charges and currents near subwavelength structures govern light transmission through subwavelength apertures ...
Quantitative determination of optical transmission through subwavelength slit arrays in Ag films: Role of surface wave interference and local coupling between adjacent slits
(AMER PHYSICAL SOC, 2008)
Measurement of the transmitted intensity from a coherent monomode light source through a series of subwavelength slit arrays in Ag films, with varying array pitch and number of slits, demonstrates enhancement (suppression) ...
Bandwidth control of forbidden transmission gaps in compound structures with subwavelength slits
(American Physical Society, 2007-12)
Phase resonances in transmission compound structures with subwavelength slits produce sharp dips in the transmission response. For all equal slits, the wavelengths of these sharp transmission minima can be varied by changing ...
Enhanced transmission via evanescent-to-propagating conversion in metallic nanoslits: role of Rayleigh anomalies
(IOP Publishing, 2014-03)
We analyze the enhanced transmission phenomenon in subwavelength slit structures near a dielectric interface. In particular, we investigate the influence of Rayleigh anomalies in the spectral position as well as in the ...
Resonances on metallic compound transmission gratings with subwavelength wires and slits
(Elsevier Science, 2006-12)
We investigate the response of gratings formed by subwavelength wires in a dielectric medium. For gratings with a single wire per period, most of the incident power is transmitted through the structure. If the distance ...
Refraction index sensor based on phase resonances in a subwavelength structure with double period
(OSA - The Optical Society, 2016-10)
In this paper, we numerically demonstrate a refraction index sensor based on phase resonance excitation in a subwavelength-slit structure with a double period. The sensor consists of a metal layer with subwavelength slots ...
Properties of TM resonances on metallic slit gratings
(OSA - The Optical Society, 2012-04)
Electromagnetic resonances on metallic slit gratings induced by TM polarized incident light have been investigated and physically interpreted. We have developed an electromagnetic model imposing surface impedance boundary ...
Striking properties of light transmitted by a double period nanoslit structure under evanescent incidence
(IOP Publishing, 2015-04)
The excitation of phase resonances in dual-period wire structures under evanescent incidence is investigated and numerically reported for the first time. The diffraction problem of a compound structure comprising subwavelength ...
Transmission through subwavelength slit structures with a double period: A simple model for the prediction of resonances
(IOP Publishing, 2009-10)
Transmission wire gratings comprising several subwavelength slits within each period (compound gratings) have been shown to exhibit abrupt dips in the transmission response. These minima correspond to phase resonances, ...
Experimental demonstration of phase resonances in metallic compound gratings with subwavelength slits in the millimeter wave regime
(American Institute of Physics, 2009-12)
We provide experimental evidence of phase resonances in metallic periodic structures in which each period comprises several subwavelength slits of the same width. We have analyzed and measured the response of these structures ...
