    • ‘Observations of the amplitude and shape of body waves at various distances and azimuths are used to study the radiation patterns and the earthquake source.’
    • ‘Palpation of trigger points often reproduces the pain radiation pattern experienced by the patient and can elicit a twitch in the muscle.’
    • ‘Antennas are usually tested for their angular response using collimated radiation to determine their far-field radiation pattern.’
    • ‘According to the reciprocity theorem, the spatial response of an antenna is exactly equivalent to its radiation pattern.’
