where o is the angle between the electric dipole p and the distance r from the dipole to the point of observation, b) Sketch a drawing (c.g., a polar plot) to describe the emission profile (power emission versus angle) of an electric dipole.(25% = 20 + 5) 3) In class we derived that the harmonic vector potential a for an electric dipole p oscillating at an angular frequency do can be described by where r is the distance from the dipole to the point of observation when the wavelength = = is much larger than the dipole size D (i.c., A )> D) a) Starting from the result above, show that the radiation pattern at frequency @ of an oscillating electric dipole is given by: S(7.
