Higher harmonic inverse free-electron laser interaction

open access: yesPhysical Review E, 2005
We expand the theory of the inverse free electron laser (IFEL) interaction to include the possibility of energy exchange that takes place when relativistic particles traversing an undulator interact with an electromagnetic wave of a frequency that is a harmonic of the fundamental wiggler resonant frequency.

Double Helical Plasmonic Antennas

open access: yesAdvanced Functional Materials, EarlyView.
Plasmonic double helical antennas funnel circularly polarized light to the nanoscale, offering strong chiroptical interaction and directional light emission. Extending a single helix design tool, this study combines numerical modeling with experimental validation, revealing large, broadband dissymmetry factors in the visible range.

Nonlinear dynamical response of interacting bosons to synthetic electric field

open access: yesPhysical Review Research, 2020
We theoretically study the nonlinear response of interacting neutral bosonic gas in a synthetically driven one-dimensional optical lattice. In particular, we examine the bosonic analog of electronic higher harmonic generation in a strong time-dependent ...

Higher harmonic resonance of duffing-type nonlinear systems excited by a force including higher harmonics.

open access: yesTRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1985
高調波ひずみをもつ外力が非線形の高調波共振応答におよぼす影響を調べるため,Duffing形の一自由度系に三次の高調波を含む外力が作用する場合の三次の高調波共振応答を求めた.調和バランス法による数値解析の結果,外力高調波成分の値により応答曲線は3種類に分類されることがわかり,それらの形の発生に対する系パラメータ依存性を明らかにした.また,RKG法による直接数値解とも比較し,結果の妥当性を確認した.

Miniature Nanomesh Mechano‐Acoustic Sensor with Wide Linear Dynamic Range, Broad Bandwidth, and Flat Frequency Response

open access: yesAdvanced Functional Materials, EarlyView.
A miniaturized mechano‐acoustic sensor is developed using an electrospun PVDF nanomesh as the diaphragm in a capacitive sensor structure. Unlike conventional nanomesh‐based sensors, it achieves high linear sensitivity, a broad and flat frequency response, and a compact form factor.

Second and higher harmonics generation with memristive systems

open access: yes, 2012
We show that memristive systems can be used very efficiently to generate passively both double and higher frequency harmonics. A technique for maximizing the power conversion efficiency into any given harmonic is developed and applied to a single ...

A local defect resonance for linear and nonlinear ultrasonic thermography [PDF]

open access: yes, 2014
An efficient wave-defect interaction is the key to a high thermal response of flaws in ultrasonic thermography. To selectively enhance defect vibrations a concept of local defect resonance is developed and applied to ultrasonic activation of defects ...

Finding, and Not Finding, “Higher Harmonic Flows” [PDF]

open access: yesActa Physica Polonica B Proceedings Supplement, 2013
Certain analysis methods have emerged recently that claim to reveal "higher harmonic flows" in more-central collisions at the RHIC and LHC. But pQCD calculations describe the same structures quantitatively.
