Beugung elektromagnetischer Zentimeterwellen an metallischen Blenden

Abstract: Abstrakt Mit Hilfe des für Hertz sehe Wellen formulierten Huyghens - Fresnel sehen Prinzips können die auf der Mittelnormalen einer kreisförmigen Blende beobachteten Beugungserscheinungen auch im Nahfeld der Öffnung quantitativ richtig beschrieben werden. Es wird gezeigt, daß dieser Ansatz mit der Kirchhoff sehen Theorie der Beugung verträglich ist und die M a x w e 11 sehen Gleichungen erfüllt.

“…Many species of phloem-feeding leafhoppers have been reported to lose their infectivity after varying periods. Ten species of leafhoppers that transmit the California aster-yellows virus lost their infectivity after 1 to 99,days (table 6) (Severin, , 1946(Severin, , 1947a. Some species retain the virus over winter.…”

“…Kirchhoff's theory may be modified in various ways to overcome some of the difficulties. 5 First, the solution to Rayleigh's equation for assumed amplitude or its normal derivative as for the unperturbed primary wave give consistent results, but these do not give correct values for both the amplitude and its derivative in the aperture. Second, a solution may be obtained which gives the unperturbed values for the amplitude and its derivative in the aperture, but then the boundary conditions are not satisfied on the screen.…”

“…An alternative approximation is the assumption that the tangential component of H is negligible at the screen, 5,15 which is equivalent to the assumption of an electric dipole layer in the aperture. A second alternative approximation is the assumption that the tangential component of E is undisturbed in the aperture, 15,16 which is equivalent to the assumption of a magnetic dipole layer in the aperture.…”
