acoustic refractionとは 意味・読み方・使い方

To obtain good group-delay characteristics while suppressing deterioration in attenuation characteristics due to refraction or the like of surface acoustic wave in a surface acoustic wave filter in which an input-side IDT electrode and an output-side IDT electrode are configured to be tapered.例文帳に追加

To solve the problem that, when a subject is pressed using a plate and an acoustic wave is received by a probe via the plate, the acoustic wave is refracted due to the difference between the sound velocity in the compression plate and the sound velocity in the subject, and a reduction in resolution occurs when the refraction is not considered.例文帳に追加

被検体をプレートで押さえ、プレート越しに探触子で音響波を受信すると、被検体とプレートに音速差があるため音響波が屈折し、その屈折を考慮しないと解像度低下が生じてしまう。 - 特許庁
