Selective Electron Beam Melting Manufacturing of Electrically Small Antennas

Advances in Science, Technology and Engineering Systems Journal, 2017
Real estate pressures in modern electronics have resulted in the need for electrically small antennas, which have subsequently garnered interest amongst researchers and industry alike. These antennas are characterized by their largest dimensions translating to a fraction of the operating wavelength; such a diminutive size comes at the expense of ...

Single-Mode Fiber Microlens with Controllable Spot Size [PDF]

, 1991
A novel method for fabricating microlenses on tapered single-mode fibers is shown to be able to control the lens spot size. The fiber cladding is first symmetrically tapered by etching it with an evaporating ammonium bifluoride solution.
