文摘

Need for high-performance and sophisticated optical devices in the terahertz wave band is growing rapidly with terahertz technological progress. This paper presents a lens in the terahertz wave band based on phase control using an oblique metal slit array. A convex oblique slit array can produce a focusing effect. This focusing effect is confirmed by full-wave analysis for the designed terahertz path-length lens. The effective refractive index computed from the full-wave analysis is consistent with analytical expressions and changes from 1.00 to 1.56 with the angle of the metal slit array. Full-wave analysis also confirms that the lamination errors of the path-length lens have limited influence on the focusing effects. The robustness of the lens design is essential for its industrial applications to terahertz optical devices.
