Unformatted text preview: (Here you have to rethink the time averaging procedure if two frequencies are involved.) Problem 3: 30 P Consider a rotation electric dipole as ~ p = p [ cos ( ωt ) ~e x + sin ( ωt ) ~e y ] Decompose the dipole moment into frequency components and use this approach to calculate the total radiated power. What is the radiation char-acteristics (angular distribution) of this dipole radiation? How does this compare to the radiated power of a dipole oscillating as ~ p cos ( ωt ) ~e x ? How can we understand these results comparing the two situations? (Here you can check that you really understood how we calulated the radiated power for the dipole.) 1...
