  8. Metamaterials (2010?) Applied for some technological applications Kymet (US) Geoscience Australia 02 March 2014

  9. Metamaterials (2010?) Radio astronomy Especially for VLBI because VLBI can use small dishes Geoscience Australia 02 March 2014

  10. Advantages 1. No moving mechanical parts 2. Slewing rate – close to infinity 3. Operation of each single element separately 4. Mitigation of RFI 5. Better efficiency – smaller size (???) Geoscience Australia 02 March 2014

  11. Problems 1. Narrow bands 2. Dual-frequency – is it practical? 3. Phase centre 4. High costs? 5. Is it affordable for geodetic applications? Geoscience Australia 02 March 2014
