Question:
When a screw is inserted in the top of a waveguide system operating in the TE10 mode, it is noticed that this will introduce a VSWR varying from unity to 3.0 for the full range of depth of insertion. That is, with the screw out, the VSWR is one; when the screw protrudes the maximum amount, the VSWR is 3.0. (a) If one thinks of the screw as giving rise to the equivalent of shunt capacitive loading, what is the corresponding range of adjustment in the equivalent per-unit reactance X/Zo? (b) Assuming the screw can be placed any arbitrary distance from the load, note on a Smith chart the range of load impedance which may be matched with this device.
