assume that the power flowing inside of a hollow rectangular waveguide carrying the te10 mode is increased until the magnitude of the electric field ey in the middle of the waveguide (where it is maximum) reaches the value ec, the breakdown field strength for the air inside of the guide. calculate the time-average power flowing down the waveguide in the z direction, in terms of the waveguide dimensions, the frequency, and the value ec. do this by integrating the poynting vector over the cross section of the waveguide. (note that the fields of the dominant te10 mode are given in the class notes.) the answer should be:
