Multiscale analysis of subwavelength imaging with metal-dielectric multilayers.
Imaging with a layered superlens is a spatial filtering operation characterized by the point spread function (PSF). We show that in the same optical system the image of a narrow subwavelength Gaussian incident field may be surprisingly dissimilar to the PSF, and the width of the PSF is not a straightforward measure of the resolution. The FWHM or standard deviation of the PSF gives ambiguous inf...
متن کاملEnhancement of localized surface plasmon resonance detection by incorporating metal-dielectric double-layered subwavelength gratings.
In this study, we investigated the enhanced sensing performance of a localized surface plasmon resonance (LSPR) biosensor by employing metal-dielectric double-layered subwavelength grating structures. The numerical results showed that the LSPR substrate with a dielectric spacer can provide not only a better sensitivity but also a significantly improved reflectance characteristic. While the pres...

متن کاملDeep subwavelength surface modes in metal-dielectric metamaterials.
We present what we believe to be the first study of deep subwavelength surface modes in binary metal-dielectric metamaterials. By employing anomalous coupling in binary periodicity, peculiar properties of band structure and eigenmode symmetry are obtained. We show that strongly confined plasmonic Tamm-like and Shockley-like surface modes can be formed at the termination of the array. We clarify...
متن کاملMetal-insulator-metal nanorod arrays for subwavelength imaging.
We proposed using metal-insulator-metal (MIM) nanorod arrays for subwavelength imaging to improve the resolution based on the notable ability of field confinement of the MIM nanorods. The field distribution of a single Au-SiO(2)-Au nanorod, coupling between two nanorods and image transfer of shaped dipole sources through nanorod arrays were investigated by using the finite-difference time-domai...
