    • PROBLEM TO BE SOLVED: To provide an element which allows a terahertz wave to be radiated with high efficiency from a high-refractive-index crystal such as a LN single crystal to an outside.SOLUTION: An electromagnetic wave radiation element 1 comprises: a body 7 made of nonlinear optical crystal; and a sub-wavelength lattice structure 5 formed on the body 7. The sub-wavelength lattice structure 5 includes: protrusions 2 arranged regularly on the body 7 in a first direction X and a second direction Y; and a first and a second groove 3X and 3Y provided between the adjacent protrusions 2 and extending toward X and Y. Each of the protrusions 2 has a pair of first surfaces 2c and 2d opposing in the X-direction, and a pair of second surfaces 2a and 2b opposing in the Y-direction. A width of the first surfaces becomes smaller in the direction from the body 7 to a top edge 2e of the protrusion, and a width of the second surfaces becomes smaller in the direction from the body 7 to the top edge 2e of the protrusion. The first groove has a curved surface when viewed in cross section in a width direction, and the second groove has a curved surface when viewed in cross section in a width direction.
    • 要解决的问题:提供一种允许以高效率从诸如LN单晶的高折射率晶体向外部照射太赫兹波的元件。解决方案:电磁波辐射元件1包括:主体 7由非线性光学晶体制成; 亚波长晶格结构5包括:在主体7上沿第一方向X和第二方向Y规则地布置的突起2; 以及设置在相邻突起2之间并朝向X和Y延伸的第一和第二槽3X和3Y。每个突起2具有在X方向上相对的一对第一表面2c和2d以及一对第二表面 2a和2b在Y方向上相对。 第一表面的宽度在从主体7到突起的顶部边缘2e的方向上变小,并且第二表面的宽度在从主体7到突起的顶部边缘2e的方向上变小。 当在宽度方向的横截面中观察时,第一凹槽具有弯曲表面,并且当在宽度方向上的横截面中观察时,第二凹槽具有弯曲表面。
