Generation of long-range curved-surface plasmonic modes and their propagation through thin metal films in a tandem array

Abstract

We describe the generation of plasmonic modes that propagate in a curved trajectory. This is performed by masking a metal surface with two screens containing a randomly distributed set of holes that follow a Gaussian statistic. The diameter of the holes is less than the wavelength of the illuminating plane wave. By implementing scaling and rotations on each screen, we control the correlation trajectory and generate long-range curved plasmonic modes. The study is generalized for the transmission of a plasmonic mode propagating in a tandem array of thin metal films using the evanescent character of the electric field.

Effectiveness of Light Source on Detecting Thin Film Transistor

“…Whereas, the peaks after filtering by the red, orange, yellow, green, and blue filters occur at 690 nm, 640 nm, 555 nm (above), 560 nm, and 450 nm respectively. As these filters were designed following the Gaussian transmission curve [13,14] to emulate the narrow spectral distribution of monochromatic LEDs, the filtered spectrum distributions conform to the filter specifications listed in Table 1. That is, they have a relatively focused wavelength to improve the image quality.…”

Asymptotic evolution of speckle patterns to synthesize non-homogeneous string beams

“…Its study and control have offered important applications in many technological areas such as microscopy, analysis of noise, image processing, etc [1][2][3][4]. Its correlation properties were implemented to generate plasmonic fields propagating on curved trajectories and to measure the blood flow speed with high accuracy [5,6]. Important physical properties can be obtained by modifying the structural features of the speckle pattern.…”
