“…When the hole diameter exceeds half of the periodicity, Bragg scattering will introduce band gaps to the dispersion relation, which correspond to different distributions of charges and electromagnetic field in space [26]. SPPs corresponding to the high order peaks have small wavelengths, so they are more sensitive to the actual size of the holes.…”

Metal films grown on Si wafer perforated with a periodic array of subwavelength holes have been fabricated and anomalous enhanced transmission in the mid-infrared regime has been observed.High order transmission peaks up to Si(2,2) are clearly revealed due to the large dielectric constant contrast of the dielectrics at the opposite interfaces. Si(1,1) peak splits at oblique incidence both in TE and TM polarization, which confirms that anomalous enhanced transmission is a surface plasmon polaritons (SPPs) assisted diffraction phenomenon. Theoretical transmission spectra agree excellently with the experimental results and confirm the role of SPPs diffraction by the lattice.

“…7b. As it has been noticed, PPs cannot be directly excited by the incident plane wave; however, PPs can interact through periodic modulations of the surface (Bonod et al, 2003;Darmanyan and Zayats, 2003;Dykhne et al, 2003;Tan et al, 2000). The effective interaction of PPs with light occurs at some resonance frequency ω = ω res (or angle of propagation α = α res ), at which their wave vectors differ by a reciprocal lattice vector K:…”

Superresolution, extraordinary transmission, total absorption, and localization of electromagnetic waves are currently attracting growing attention. These phenomena are related to different physical systems and are usually studied within the context of different, sometimes rather sophisticated, approaches. Remarkably, all these seemingly unrelated phenomena owe their origin to the same underlying physical mechanism -wave interaction with an open resonator. Here we show that it is possible to describe all of these effects in a unified way, mapping each system onto a simple resonator model. Such description provides a thorough understanding of the phenomena, explains all the main features of their complex behavior, and enables to control the system via the resonator parameters: eigenfrequencies, Q-factors, and coupling coefficients.

“…Many different theoretical approaches have since been adopted, all replicating the normal incidence transmission spectra [3][4][5][6][7]; consequently, more than just the normal incidence transmission spectrum needs to be explored if one is to obtain a clearer picture of the underlying physics. Despite a convergence of views among many theorists that the enhanced transmission involves multiple diffraction enhanced by SPPs [5][6][7][8][9], there remains some controversy surrounding the transmission mechanism; not all authors agree that surface plasmons are involved. (Note that explanations based on results from 1D arrays of slits cannot be used, and the physics is very different; sub-=2 slits can support propagating modes, while sub-=2 holes cannot [10].)…”

Surface Plasmon Polaritons and Their Role in the Enhanced Transmission of Light through Periodic Arrays of Subwavelength Holes in a Metal Film

We present results of the transmitted, reflected, and absorbed power associated with the enhanced transmittance of light through a silver film pierced by a periodic array of subwavelength holes. Comparing experimentally acquired dispersion curves under different polarization conditions shows that the transmission features of the array are consistent with p-polarized resonant modes of the structure. By exploring the regime in which no propagating diffracted orders are allowed, we further show that the transmittance maxima are associated with both reflectance minima and absorption maxima. These new results provide strong experimental evidence for transmission based on diffraction, assisted by the enhanced fields associated with surface plasmon polaritons. DOI: 10.1103/PhysRevLett.92.107401 PACS numbers: 78.20.Ci, 41.20.Jb, 42.25.Fx, 73.20.Mf The observation of the enhanced transmission of light through a metallic film perforated by an array of subwavelength holes [1] sparked a wealth of research seeking to explain the underlying physics. For light of wavelength , a hole less than =2 in diameter in a thick metal film does not support any propagating modes; energy can propagate only by an evanescent tunneling process leading to very weak transmittance -in marked contrast to the experimental observations.Initial explanations considered coupling of the incident light via diffraction to surface plasmon polariton (SPP) modes of the metallic structure [1,2]. Many different theoretical approaches have since been adopted, all replicating the normal incidence transmission spectra [3][4][5][6][7]; consequently, more than just the normal incidence transmission spectrum needs to be explored if one is to obtain a clearer picture of the underlying physics. Despite a convergence of views among many theorists that the enhanced transmission involves multiple diffraction enhanced by SPPs [5][6][7][8][9], there remains some controversy surrounding the transmission mechanism; not all authors agree that surface plasmons are involved. (Note that explanations based on results from 1D arrays of slits cannot be used, and the physics is very different; sub-=2 slits can support propagating modes, while sub-=2 holes cannot [10].) As noted elsewhere [8], the experimental evidence obtained thus far is consistent with the involvement of SPPs rather than conclusive about their involvement. We present new experimental data not just of the transmittance, but also of the reflectivity and absorbance. We investigate two unexplored far-field signatures of SPPs in this context, their polarized nature and their dissipative character; we are thus able to identify the role played by SPPs in the transmission process.Diffraction is central to the transmission process. Diffraction of the incident plane wave by the array produces waves with the required evanescent character; diffraction of the transmitted evanescent wave on the far side of the array then produces the propagating transmitted light. However, these diffraction processes are independent of the...
