摘要：
Analysis of optical structures that can work for a broadband range of THz radiation is the aim of this article. Such structures can be designed as kinoforms of higher order or elements with an extended depth of focus, like axicons or light sword elements. A theoretical and experimental comparison of different optical elements for three significantly different frequencies is performed.
