18.0 Some high-frequency math
62
In contrast, if E is not known, calculation of
S
is still possible as follows:
Should you wish to calculate the electric field
E
, use the following formula:
The magnetic field
H
can be calculated as follows:
18.1 Calculation of wavelength
Wavelength can be calculated using the formula:
Here, c corresponds to the speed of light in [m/s] (rounded to 300.000km/s in our
example), f to the frequency of the radiation in [Hz], and to the wavelength
in [m].
Examples:
(For 900 MHz, the result is 0,33m)
(For 1,8 GHz, the result is 0,17m)
(For 2 GHz, the result is 0,15m)
Further information concerning wavelength is contained in table 4 on page
