Field and Wave Electromagnetics 2nd Edition by David Cheng

تمرين 15

Measurements at 10 (GHz) on an X-band air-filled rectangular waveguide (a = 2.29 cm, b = 1.02 cm) connected to an unknown load indicate a minimum electric field at 6 (cm) from the load and a standing-wave ratio (SWR) of 1.80. Find the location and the dimensions of a symmetrical capacitive iris required to bring the SWR to unity.
