Resonance Far-field Accelerating Structures at Short Wavelengths

چکیده

Resonance far-field structures capable to provide high gradient continuos acceleration at millimeter and micron wavelengths are considered. Among such structures are periodically striped open waveguide and oversized waveguide having periodic small perturbations. Main parameters of the structure composed by flat mirrors are estimated on the base of rigorous analytical solution for the eigenmodes. Some modifications of diffraction-dominated structures based on open waveguides and resonators are proposed.

Nanogap effects on near- and far-field plasmonic behaviors of metallic nanoparticle dimers.

In the field of plasmonics, the nanogap effect is often related to one aspect like the near-field enhancement at a single excitation wavelength or the far-field resonance shift. In this study, taking full advantage of finite element method (FEM) calculations, we present a comprehensive and quantitative analysis of the nanogap effect on the plasmonic behaviors of metallic nanoparticle dimers. Fi...

Magnetic resonance imaging of feline eye

The purpose of this study was to investigate magnetic resonance imaging (MRI) of the normal feline eyeand optic nerves using T1-weighted and T2-weighted images. A total of 6 healthy female domestic short haircats age 2-2.5 years and weighing 3.2 ± 0.4 kg were selected. Magnetic resonance imaging data werecollected using GEMSOW (Philips) at a magnetic field strength of 1.5 T. Dorsal, sagittal, a...

Preliminary Results on Open Accelerating Structures

Conventional accelerating structures consist of cavities or enclosed transmission lines with the particles to be accelerated passing along the axis of the enclosure. Electromagnetic modes can be excited within such structures with electric components in the direction of the particle motion. Their wave velocity is inevitably less than that of light unless the cavity is loaded with a dielectric o...

Evaluation of Nonlinear Dynamic Response of Rigid and Semi-Rigid Steel Frames under Far-Field Earthquake Records

The purpose of this research was to evaluate the nonlinear dynamic response of rigid and semi-rigid steel frames under Far-Fault Earthquake Records. Accordingly, the fragility curve of the moment frames with rigid and semi-rigid connections was determined. Considering the analytical knowledge of structures in the past, the analysis and design of steel frames based on the assumptions of rigid or...

Near-field investigation of the effect of the array edge on the resonance of loop frequency selective surface elements at mid-infrared wavelengths.

Mid-infrared scattering scanning near-field optical microscopy, in combination with far-field infrared spectroscopy, and simulations, was employed to investigate the effect of mutual-element coupling towards the edge of arrays of loop elements acting as frequency selective surfaces (FSSs). Two different square loop arrays on ZnS over a ground plane, resonant at 10.3 µm, were investigated. One a...
