Tenmars TM-195 - Power Density (S); The Characteristic of Electromagnetic Fields

expressed in units of amperes per meter (A/m). In far field
situations, one can calculate the magnetic field for the electric
field value. This meter can display the calculated magnetic field
strength.
3.3 Power density (S):
Power per unit area normal to the direction of propagation,
usually expressed in units of watts per square meter (W/m
2
) or,
for convenience, units such as mill watts per square centimeter
(mW/cm
2
).
3.4 The characteristic of electromagnetic fields:
Electromagnetic fields propagate as waves and travel at the
speed of light (C). The wavelength is proportional to the
frequency.
