Numerical analysis of a slit-groove diffraction problem
نویسندگان
چکیده
We present a comparison among several fully-vectorial methods applied to a basic scattering problem governed by the physics of the electromagnetic interaction between subwavelength apertures in a metal film. The modelled structure represents a slit-groove scattering problem in a silver film deposited on a glass substrate. The benchmarked methods, all of which use in-house developed software, include a broad range of fully-vectorial approaches from finite-element methods, volume-integral methods, and finite-difference time domain methods, to various types of modal methods based on different expansion techniques.

Effect of the Slit’s Thickness to the Electromagnetic Plane Wave Scattering
Electromagnetic wave diffraction by a wide and thick slit has been formulated and analyzed the effect of the slit’s thickness. From our numerical calculation, it has been found that for far field pattern, one can apply a rather simple infinitely thin slit formulation, when the thickness of the wide slit is less than one half wavelength. keywords: Ray-mode coupling, Thick slit diffraction proble...
متن کاملThe Metron Model: a Unified Deterministic Theory of Fields and Particles – a Progress Report
Metron computations of the double-slit diffraction of a particle beam are in good agreement with quantum theory, demonstrating that wave-particle duality can be explained quantitatively within the framework of a deterministic particle model. Preliminary forwardmodelling computations of the structure the electron are consistent with previous metron predictions from inverse modelling, but work on...
متن کاملGaussian Beam Summation for Diffraction in Inhomogeneous Media Based on the Grid Based Particle Method
We develop an efficient numerical method to compute single slit or double slit diffraction patterns from high frequency wave in inhomogeneous media. We approximate the high frequency asymptotic solution to the Helmholtz equation using the Eulerian Gaussian beam summation proposed in [20, 21]. The emitted rays from a slit are embedded in the phase space using an open segment. The evolution of th...
متن کاملNear-field surface plasmon effects on Au-double-slit diffraction for polychromatic light
The surface plasmon effects on near-field diffraction for polychromatic light are studied. An Au-double-slit is used as the model and Fresnel integral is employed to perform the theoretic analysis. The results are illustrated with numerical examples and they show that, compared with the normal double-slit, the plasmon effect changes the spectral shift from redshift to blueshift and also enhance...
