Webb1 jan. 2013 · They are all geometric shape sensitive and altogether act to induce the shape resonance effect of SHG from these nanostructured gold thin films. In short, the SHG shape resonance can be ascribed to the strongly shape dependent intrinsic phase and attenuation feature of the FW and SHW waveguide mode and the external excitation … WebbLong-range surface plasmon resonance (LRSPR), generated from a coupled plasmon polariton in a thin metal slab sandwiched by two dielectrics, has attracted more and more attention due to its merits, such as longer propagation and deeper penetration than conventional single-interface surface plasmon resonance. Many useful applications …

A shape resonance is a metastable state in which an electron is trapped due to the shape of a potential barrier. Altunata describes a state as being a shape resonance if, "the internal state of the system remains unchanged upon disintegration of the quasi-bound level." A more general discussion of resonances and their … Visa mer In quantum mechanics, a shape resonance, in contrast to a Feshbach resonance, is a resonance which is not turned into a bound state if the coupling between some degrees of freedom and the degrees of freedom … Visa mer • Fano resonance Visa mer Webb26 jan. 2024 · In its simplest form, resonance occurs when an object experiences an oscillating force that’s close to one of its “natural” frequencies, at which it easily … maler theesfeld norden

WebbShape resonances, on the other hand, may be associated with the shape of a trapping potential in real, coordinate space. Most often, the trapping potential is an angular … WebbShape Resonance. Dragging the energy through the region with the narrow potential barrier ( E =600–1350), note how the amplitude of the wavefunction resides "outside" this barrier. But also observe how there seem to be discontinuities or jumps at certain energies. Examine one of these regions closely.
