Resonance Cones in Magnetized Plasma
An experimental investigation of ion and electron resonance cones have been carried out in the toroidal device Thorello in which a weakly magnetized plasma is produced. As resonance cones propagation depends on foundamental parameters of plasma, we can estimate density, temperature, magnetic field and ion minority concentration. In this way the investigation aims to develop some plasma diagnost...
متن کاملFocusing Light with Curved Guided-Mode Resonance Reflectors
Employing numerical simulations, we investigate the possibility of using curved guided-mode resonance (GMR) elements to focus light in reflection. We treat GMR reflectors with a parabolic shape and show that they are capable of focusing light effectively across wavelength bands that extend several hundred nanometers. The spatially infinite reflector model is simulated with a finite-element meth...
متن کاملIndecomposable Cones
We study some relations between a reproducing cone K in a linear space V over a fully ordered field F and the cone I(K) in Hom( V, V) consisting of all operators A such that AK G K. In particular, indecomposable cones are considered.
متن کاملAlgebraic Cones
A characterization of algebraic cones in terms of actions of the onedimensional multiplicative algebraic monoid Mm and the algebraic group Gm are given. This note answers a question of K. Adjamagbo asked in [A]. Below all algebraic varieties are taken over an algebraically closed field k. An irreducible algebraic variety X is called a cone if X is affine and its coordinate algebra k[X ] admits ...
متن کاملMulti-phase coronary magnetic resonance angiography using a 3D cones trajectory
Methods Axial slabs covering the whole heart were imaged on a GE Signa 1.5 T Excite system using a surface coil. Following detection of the cardiac trigger and delay TD (Fig. 2), a 2D sagittal spiral navigator image (3-mm resolution) containing the left ventricle was acquired for respiratory motion tracking. Ten catalyzation cycles were then played out to establish the steady state for 3D cones...
