The Difference

In this paper, the radome materials suitable for mid-infrared /millimeter wave multimode were introduced, as well as the properties. In comparison with the difference of the radome materials, the polycrystalline magnesium fluoride was promising for the radome of mid-infrared /millimeter wave multimode. Furthermore, the millimeter wave transparent properties of polycrystalline magnesium fluoride were studied by the simulation based on moment method and multilevel fast multipole method.

Made In

The following are the main improvements that we have made in the method of phase-contrast microscopy described by Kempson, Thomas, and Baker (1948): 1. No bull's-eye condenser is used. The illuminant is an electric bulb with a ‘porcelain-processed’, ‘flashed white’, or ‘opal’ surface. 2. No oiled paper is placed over the illuminating annulus. 3. The thickness of the deposit of magnesium fluoride on the phase-plate is controlled by observations on the interference colours given by surface reflections. 4. Positive (dark) phase-contrast is preferred for most purposes to negative (bright).
