The university-compiled manual I'm working with states the following:
At small amplitudes the diode voltage is approximately proportional to microwave intensity; this, in turn, is proportional to the square of the E-field amplitude.
But this follows:
At higher levels the diode voltage...
Right, I did read that. Unfortunately we seem to be using an older version of the apparatus. Our receiver didn't actually have a meter on it. We hooked it up to a voltmeter to take measurements.
Homework Statement
We're working through the first Microwave Optics lab described in the following PASCO Scientific manual:
intro.phys.psu.edu/class/p457/experiments/html/pasco_microwave_optics_WA-9314B.pdf
We're using a slightly modified version of this setup, with a voltmeter hooked...
Can you speak more about what the r_il and r_jl elements map to, using the coordinates used in this problem? Specifically, what is 0 and what is a/-a? I'm having a brain-cramp about it... and I know it's something straightforward.
