Hello all,
I have a problem regarding E and H field generation inside a TEM cell. I have built a standard cell with Zw of 150 Ohms, which I need to generate a known magnetic field strength around 90 MHz. The separation of the top and bottom conductor is 25 cm, the overall length is about 130 cm.
But I don't get the expected results, only at lower frequencies up to 20 MHz the results are usable. At higher frequencies I suspect that I get a standing wave inside my room, or that the cell dimensions in itself are so large compared to the wavelength, that I get an unwanted resonance inside the cell.
I have been looking for material about this in the 'net, but so far I have not found pay dirt.....
What am I missing here???
