What reading level is Electromagnetic Oscillations From a Bent Antenna a Dissertation Presented to Th book?
To quickly assess the difficulty of the text, read a short excerpt:
0212 180 30 . 0211 150 45 . 0206 135 60 . 0209 120 .
90 . 0207 90 2000 . 0206 180 30 . 0197 150 60 . 0199 120 90 . 0196 90 The symmetry of the curves developed from the theory can be reconciled with the asymmetrical curve found in the experi- ments by supposing that the electrical waves brought back to the earth from high in the atmosphere are more intense toward the bend in the antenna than at the free end. Zenneck (Zenneck, Phys. Zeitsch. , Vol. 9, p. 553, 1908) has shown that this difference... may be due to imperfect conductivity in the earth's surface.
SUMMARY First : The equations developed by Pocklington, Abraham and Peirce have been applied to an antenna with vertical and horizontal parts in such a way as to find the energy given out for the fundamental vibration: X = 4(fc + d) Second: The intensities so obtained are plotted and are shown to have a fore and aft directive inclination. The intensity fore and aft is symmetrical and not asymmetrical as required by the experiments.
FROM A BENT ANTENNA 15 Third: Close to the antenna the intensities are symmetrical in azimuth agreeing with experiment.
