Dependence on Frequency of the Electromagnetic Field Distribution inside a Cylindrical Cavity
Excited through an Off-Axis Aperture
Figure 2
Modulus of the electric field without the term 1/ 1 ( in the plane z = L/2 for modes close to the
14 GHz frequency for 1 W of the incoming wave power. For each mode the maximum
field value is estimated after an equal time interval, supposed large enough to
neglect the second-order terms. The white normal axes indicate the mode
rotation caused by the coupling with the rectangular waveguide.
