Abstract
A terahertz device includes an antenna base including reflective films, wherein: the reflective films are curved to be recessed; the reflective film and the reflective film are arranged to be adjacent to each other in a y direction; and when viewed from a z direction, the sizes of the reflective film and the reflective film along an x direction are smaller than the sizes of the reflective film and the reflective film along the y direction.
Claims22
A terahertz device, comprising:
- terahertz elements including a first terahertz element and a second terahertz element configured to receive an electromagnetic wave;
- and
- reflective surfaces including a first reflective surface and a second reflective surface, the first reflective surface being opposed to the first terahertz element in a thickness-wise direction of the first terahertz element to reflect an incident electromagnetic wave toward the first terahertz element, and the second reflective surface being opposed to the second terahertz element in a thickness-wise direction of the second terahertz element to reflect an incident electromagnetic wave toward the second terahertz element, wherein
- the first reflective surface is opened toward the first terahertz element and is curved to be recessed in a direction away from the first terahertz element,
- the second reflective surface is opened toward the second terahertz element and is curved to be recessed in a direction away from the second terahertz element,
- when a direction parallel to the thickness-wise direction of each of the terahertz elements is referred to as a height-wise direction of the terahertz device, the first reflective surface and the second reflective surface are arranged adjacent to each other in a first direction that intersects the height-wise direction of the terahertz device, and
- as viewed in the height-wise direction of the terahertz device, at least one of the first reflective surface and the second reflective surface is smaller in the first direction than in a second direction that differs from the first direction.

A terahertz device, comprising:
- terahertz elements including a first terahertz element and a second terahertz element configured to generate an electromagnetic wave;
- and
- reflective surfaces including a first reflective surface and a second reflective surface, the first reflective surface being opposed to the first terahertz element in a thickness-wise direction of the first terahertz element to reflect the electromagnetic wave generated by the first terahertz element in one direction, and the second reflective surface being opposed to the second terahertz element in a thickness-wise direction of the second terahertz element to reflect the electromagnetic wave generated by the second terahertz element in one direction, wherein
- the first reflective surface is opened toward the first terahertz element and is curved to be recessed in a direction away from the first terahertz element,
- the second reflective surface is opened toward the second terahertz element and is curved to be recessed in a direction away from the second terahertz element,
- when a direction parallel to the thickness-wise direction of each of the terahertz elements is referred to as a height-wise direction of the terahertz device,
- the first reflective surface and the second reflective surface are arranged adjacent to each other in a first direction that intersects the height-wise direction of the terahertz device, and
- as viewed in the height-wise direction of the terahertz device, at least one of the first reflective surface and the second reflective surface is smaller in the first direction than in a second direction that differs from the first direction.
