| Popis: | A spintronic heterostructure consisting of Pt and Fe thin films deposited by magnetron sputtering on a convex glass lens is demonstrated as a terahertz emitter. The experimental results show that the convex type spintronic terahertz emitter focuses its radiated terahertz beam without the need for any additional optics, thereby allowing opportunities for the simplification of terahertz setups. |
