    • Laser-micromachined millimeter-wave photonic band-gap cavity structures 

      Özbay, E.; Tuttle, G.; McCalmont, J. S.; Sigalas, M.; Biswas, R.; Soukoulis, C. M.; Ho, K. M. (American Institute of Physics, 1995)
      We have used laser-micromachined alumina substrates to build a three-dimensional photonic band-gap crystal. The rod-based structure has a three-dimensional full photonic band gap between 90 and 100 GHz. The high resistivity ...
