Electric Fields Induced in
Cells in the Bodies of Amateur Radio Operators by
Their Transmitting Antennas
Ronold W. P. King Life Fellow, IEEE
Page 2155.
Abstract:
In this paper, an analytical study is made to determine the electric
field induced in cells in the bodies of amateur radio operators by radiation
from their respective transmitting antennas. Three types of antennas are considered
and the electric field from each in the transmitting room of the operator
is calculated. The electric field induced in the bodies of the operators is
obtained with a cylindrical approximation of the body. The electric field
induced in a cell in the central cross section of the body at
f = 60 MHz when the antenna radiates 1 kW is found to be
as high as 50 V/m when the cell is near the surface. Due to skin effect, the
field is much smaller in the interior of the body.
