Abstract

Official abstract text for this publication.

An infrared sensor is formed in such a manner that an infrared receiver and a base substrate are spaced with a beam made of a thin-film phononic crystal in which through holes are arranged periodically. The beam made of a phononic crystal is formed in such a manner that a period P of through holes increases at arbitrary intervals in a direction from the infrared receiver toward the base substrate.

First claim

Opening claim text (preview).

What is claimed is: 1. A thin film having a substantially rectangular shape in a plain view, the thin film comprising: a first domain; a second domain; and a third domain, wherein: the first domain is located between the second domain and one end of a longitudinal direction of the thin film in the plain view, the first domain is formed of a phononic crystal comprising through holes arranged regularly at a period p1, the second domain is located between the first domain and the third domain in the plain view, the second domain is formed of a phononic crystal comprising through holes arranged regularly at a period p2, the third domain is located between the second domain and other end of the longitudinal direction of the thin film in the plain view, the third domain is formed of a phononic crystal comprising through holes arranged regularly at a period p3, a value of the period p2 is greater than a value of the period p1, and a value of the period p3 is greater than a value of the period p2. 2. A method of using a thin film having a substantially rectangular shape in a plain view, the method comprising: generating a temperature gradient in the thin film towards one end of a longitudinal direction of the thin film from other end of the longitudinal direction of the thin film, wherein: the thin film includes a first domain, a second domain, and third domain, the first domain is located between the second domain and the one end in the plain view, the first domain is formed of a phononic crystal comprising through holes arranged regularly at a period p1, the second domain is located between the first domain and the third domain in the plain view, the second domain is formed of a phononic crystal comprising through holes arranged regularly at a period p2, the third domain is located between the second domain and the other end in the plain view, the third domain is formed of a phononic crystal comprising through holes arranged regularly at a period p3, a value of the period p2 is greater than a value of the period p1, and a value of the period p3 is greater than a value of the period p2.
