Question
In antenna theory, this regime holds beyond a distance defined as either twice wavelength or twice dimension-squared over wavelength. For 10 points each:
[10h] Name this regime in which the angular field distribution is independent of distance from the antenna. In this regime, diffraction is modeled as the result of in-phase plane waves.
ANSWER: far field [prompt on answers describing being far away from the source or having large distance from the source; prompt on Fraunhofer diffraction]
[10m] Receiving antennae are contrasted with antennae that perform this process. This process, whose coefficient equals one minus the reflection coefficient, precedes power distribution in namesake "lines."
ANSWER: transmission [accept word forms like transmitting; accept transmission lines]
[10e] Power patterns of antennae are often given in this log-scale unit. This is the typical unit for the volume of sound.
ANSWER: decibels [prompt on dB]
