Resonant Scattering by a Multilayered Grating

PIERS Online, 2005
We investigate resonance absorption of incident light energy in a multilayered grating, which is a stack of metal and dielectric films periodically corrugated in one direction. The absorption is associated with two kinds of resonant scattering in a multilayered structure: excitation of coupled surface plasmons on a thin metal film and resonance of ...

Multilayer resonators with fractal morphology for microwave heating

ICECom 2013, 2013
A fractal Cantor dielectric multilayer is a stack of two different dielectric layers whose thicknesses are chosen according to the Cantor procedure. At a given frequency, by properly designing the multilayer it is possible to obtain in some regions of the resonator a field intensity significantly greater than that of the incident one. Such a phenomenon,

Resonance diffraction efficiency enhancement in sliced multilayers

Applied Optics, 1993
The theory of transmission and reflection sliced multilayers is considered. The possible scheme of a high throughput and resolution spectrograph for the 124-250-A range is proposed.

Resonant diffraction of synchrotron radiation by a nuclear multilayer

Physical Review Letters, 1993
We report the observation of nuclear resonant diffraction of synchrotron radiation by a synthetic multilayer. The nuclear period of the ${[}^{57}$Fe(22 \AA{})/Sc(11 \AA{})/Fe(22 \AA{})/Sc(11 \AA{})\ifmmode\times\else\texttimes\fi{}25 multilayer was chosen to be twice the electronic period to obtain a pure nuclear Bragg reflection. Strong enhancement of

Resonant scattering by multilayered dielectric gratings

Journal of the Optical Society of America A, 1997
The diffracted orders generated by a plane-wave incident upon a multilayered dielectric grating can undergo strong intensity variations known as Wood’s anomalies or scattering resonances. To clarify these effects, we examine the field and power flux inside the grating region by using a rigorous modal solution of the scattering problem. The results show

Ferromagnetic Resonance in Multilayer Perpendicular Films

IEEE Transactions on Magnetics, 2016
Ferromagnetic resonance measurements can provide valuable information about thin-film structures, including recording media. This paper develops analytic expressions for the behavior of continuous-coupled multilayer perpendicular films and compares these with micromagnetic simulations.

Resonant states and currents in superconducting multilayers

Physica C: Superconductivity, 2001
Abstract We calculated electronic states and Josephson currents for superconducting multilayers with one-dimensional SISIS and SNSNS junctions, where S is a superconductor, I, an insulator, and N, a normal metal. We obtained numerical solutions of the Bogoliubov–de Gennes equations for the case where the Fermi wavelength of quasi-electrons and quasi ...

Resonance frequencies of the multilayered piezotransducers

The Journal of the Acoustical Society of America, 2008
Piezoelectric transducers used in high power ultrasonic applications are composed of piezoelectric ceramics, metallic blocks and a central bolt that pre-stresses the assembly. The impedance characterization of these transducers has been done by using numerical methods but, in many cases, one-dimensional simplified models are enough to a good physical ...

A Composite, Multilayered Cylindrical Dielectric Resonator

MTT-S International Microwave Symposium Digest, 2005
The analysis of TE modes in a composite multilayered cylindrical dielectric resonator is presented. All cylindrical dielectric resonator structures which have found some practical applications can be treated as a special case of the structure under consideration. These include: single resonator, double resonator, ring resonator, resonator in microstrip,

Spin-Wave Resonance in Multilayer Films

Solid State Phenomena, 2010
For the first time characteristic modification of a spectrum of the exchange spin waves, caused by the first stop-band at a wave vector kb=π/(d1+d2) the magnon crystal formed by one-dimensional modulation of the exchange or magnetization has been found by the spin-wave resonance (SWR) technique in multilayer structures “ferromagnet/ferromagnet” with N ...
