I give the following example: If we load a generator directly with a
resistance of 10 ohms, without any transmission line, there are not
traveling waves interfering, therefore there are not stationary waves,
there is only a impedance mismatch affecting the source voltage ¿OK?.
If then I load it with a line of half wave finished in the same 10
ohms resitance, the generator "will see" a 10 ohms load, and it will
behave identically as it made it with the original "direct" load.
In both cases there is not reflected power that it can return to the
generator...

I used a similar problem in my discussion entitled "A simple VSWR
analysis without mirrors" at http://vk1od.net/blog/?p=1259. The article
then goes on to solve a real problem (ie a practical low loss line
rather than the lossless line in the first example, and in your example.

You should find them relevant.
