WebApr 15, 2024 · The frequency range for all the chirped SAW-IDT has been set from 20 to 125 MHz. Then, a length of 4 mm was imposed for the patterns (along the IDT axis Ox (Fig. 2). As a result, the duration of generated wave did not exceed 1 μs. For the most of studied structures this is sufficient to obtain rather high SAW displacement amplitudes and to ...

WebAn integrated-optic Fourier processor consisting of an acoustooptic (AO) deflector and graded-index Fresnel lenses in an As2S3 waveguide on a SiO2/Si substrate is proposed and the prototype device is demonstrated. For the interdigital transducer (IDT) for surface acoustic wave excitation, a two-stage array of uniform-period IDT and a chirped IDT … WebSep 7, 2024 · Here, we address this challenge by demonstrating single-shot chirp synthesis of a strongly compressed acoustic pulse. Employing this solitary SAW pulse to transport a single electron between distant quantum dots with an efficiency exceeding 99%, we show that chirp synthesis is competitive with regular transduction approaches.
WebChirped gratings tend to have lower side-mode structure in their reflection spectra to begin with, and the advantage of apodization is in the reduction of internal interference effects that cause the group delay to acquire a ripple. http://www.freedictionary.org/?Query=Chirped
WebNational Center for Biotechnology Information WebThe development of microfluidic chip-based cytometers has become an important area due to their advantages of compact size and low cost. Herein, we demonstrate a sheathless microfluidic cytometer which integrates a standing surface acoustic wave (SSAW)-based microdevice capable of 3D particle/cell focusing with a laser-induced fluorescence (LIF) …
WebTwo orthogonal pairs of chirp interdigitated transducers (IDT) were fabricated by a metal deposition and lift-off process on top of a lithium niobate (LiNbO 3) piezoelectric substrate. A 2.5 × 2.5 mm 2 PDMS channel was bonded to the substrate asymmetrically between these two pairs of IDTs ( Fig. 3A ).
