SURFACE WAVE AND ANTENNA ENGINEERING RESEARCH STUDY.
Abstract
A phase correcting lens to be used in conjunction with a diagonal horn was designed and fabricated. Measurements show that the field of this horn and phase corrector combination closely simulates the field of the lowest loss made of the beam waveguide. The effectiveness of the horn-lens combination as a launcher of the beam waveguide mode must yet be measured. A method for measuring the dielectric constant of gases using a dual mode beam waveguide resonator was devised. The dielectric constant of dry air at various pressures has been measured at a frequency of 34 Gc. The value obtained at standard pressure and temperature agrees to within 0.0005% of that given by the Bureau of Standards for a frequency of 9 Gc. (Author)
