Designer blue beams

Designer pulsed beams for enhanced space-time focusing.

We have demonstrated analytically and numerically that at least 10-100-fold enhancements in intensities for similar input energies can be achieved in the focal region of a thin dielectric lens by the use of pulsed beams specifically designed for that purpose.

Designer spoof surface plasmon structures collimate terahertz laser beams.

Surface plasmons have found a broad range of applications in photonic devices at visible and near-infrared wavelengths. In contrast, longer-wavelength surface electromagnetic waves, known as Sommerfeld or Zenneck waves, are characterized by poor confinement to surfaces and are therefore difficult to control using conventional metallo-dielectric plasmonic structures. However, patterning the surf...

Designer Prussian Blue Analogues Molecular Magnets with Possible Applications

Magnetic materials are the key components of many electronics devices for storage and retrieval of information, such as computer hard drives and video tapes. Magnetic materials are also in high demand in power generation, non-polluting electric vehicles, medical science, telecommunication, etc. Due to wide technological applications of magnetic materials, there have always been quests for new m...

‘Designer’ babies

The remaining hurdle to the creation of babies specifically to save the life of an ailing brother or sister was removed in Britain last month by the fertility regulatory body to the delight of afflicted families and alarm of those who fear the advent of a 'designer' baby age. The decision of the UK's Human Fertilisation and Embryology Authority gives new hope to the parents of a two-year-old bo...
