A conventional binary zone plate for terahertz focusing is compared with a proposed new configuration in which two zone plates are stacked, showing an increased focusing efficiency. The field intensity in the focal spot is enhanced by employing a low-loss cyclo-olefin polymer instead of more conventional materials.

Abstract
A conventional binary zone plate for terahertz focusing is compared with a proposed new configuration in which two zone plates are stacked, showing an increased focusing efficiency. The field intensity in the focal spot is enhanced by employing a low-loss cyclo-olefin polymer instead of more conventional materials.File in questo prodotto:
