Fig. 15 shows a plot of the electric field components Ei and E2 as a function of time for various values of 9. 8, shows that, for 9 = 90°, the radiation is concentrated in very narrow pulses having a typical width of the order of one tenth of the period, and that the component E\ of the electric field is identically zero. This means that the spectrum of the radiation is very broad, extending to frequencies much higher than the synchrotron frequency u>s (UP to ~ 10ws in this case), and that the radiation is totally linearly polarized the direction of polarization being perpendicular to the magnetic field.

Indeed, denning the total power of the radiation emitted through the equation W = / Wu dco , Jo one finds that the integral diverges.
