A Packard-Varian type experiment was done, in which the free precession of proton magnetic moment about a very weak magnetic field was observed, by first lining up the protons in an aqueous sample with a separate magnetic field and then allowing them to execute the free precession. In out experiment the studies on the non-adiabatic process of withdrawing the polarizing field, the absolute value of the signal strength and the reduction of sample size to minimize the effect of inhomogeneity of...

A Packard-Varian type experiment was done, in which the free precession of proton magnetic moment about a very weak magnetic field was observed, by first lining up the protons in an aqueous sample with a separate magnetic field and then allowing them to execute the free precession. In out experiment the studies on the non-adiabatic process of withdrawing the polarizing field, the absolute value of the signal strength and the reduction of sample size to minimize the effect of inhomogeneity of the magnetic field were emphasized. The effect of rotating the sample coil upon the measured signal frequency was also noted, and it is pointed out that this is the most direct way to determine the sign of the nuclear magnetic moment.

Using curves and formulas given in the paper, the design and calculation may be very simple. Experiments have shown that within about...

This paper gives two kinds of circular polarizer made of several pho to-etched copper strip or strip-grid fiberglass epoxy plates. One is called strip type, the other strip-grid type. The former has good performances at center frequency, the latter has broad-band performance. These two polarizers may be made into a polarized board as a cover set in front of the waveguide horn. Using curves and formulas given in the paper, the design and calculation may be very simple. Experiments have shown that within about 20% of the band-width of the strip type polarizer the axial ratio of circular polarized field is better than 2 dB and VSWR less than 1.1, and that within more than 20% of the band-width of the strip-grid type polarizer the axial ratio of circular polarized field is better than 1dB and VSWR less than 1.1.

This article is based on the principle of power conservation, which has taken substan-tially the mutual interaction effects between spaced aperatures in multiaperature couplersinto account, that is, to treat electromagnetic fields scatterrd by the individual aperatures aspart of the polarizing field acting on an aperature. The new theory gives the correctionfactors improving the multiaperature coupling theory. To compare the couplings of 2 and 3pairs of hole measured by experiments with the theoretical predictions shows that the newtheory is better in agreement with the experiments than some previous theory[5].
