millimeter waves
1.Experimental Study of a Leaky Wave Antenna for Millimeter Waves Using Nonradiative Dielectric Waveguide
2.Millimeter-waves inverse Cassegrain antenna with polarization-rotation, efficient wide scan angle,light weight and small size, which is used in modern radar systems, is studied in this paper.
3.Finally, the corrections of the relative frequency characteristic of tesseral and zonal harmonic waves are re-calculated by using the precise development of TGP presented lately to replace the TGP of Cartwright & Tayler(1971)development adopted in the IERS2000.The results indicates that there are the differences of both the corrections in the sub-millimeter level from that in IERS2000,it is necessary to account those differences in present space geodesy.
