Schematic of the principle of coherent scattering of electromagnetic waves from a moving e-h plasma boundary in a transmission line fabricated on the surface of a semiconductor substrate.
Block diagram of the experimental apparatus.
Oscilloscope traces of the output signals from the SBD detector for different values of the input frequency .
Measured delay times as a function of the input frequency. Continuous curve represents the theoretical fit to the measurement values.
Output signal voltages as measured with the SBD diode detector as a function of the input frequency for three different waveguides at the -, -, and -bands. Signal voltages are normalized to the maximum value of 150 mV for the -band waveguide at 13.5 GHz. Measured values for the -band waveguide are multiplied by 3.
