Abstrak

A simulation model of the CW-EPR (continuous wave electron paramagnetic resonance) system’s signal transmission, modulation, and detection is constructed using the Simulink platform. The model supports signal source simulation, modulation, detection by the Schottky diode detector, and lock-in amplifier-assisted demodulation. Using this model, we characterize how 5,5-dimethyl-1-pyrroline N-oxide (DMPO) samples’ spectra vary with modulation amplitudes and phases. Consistency is observed between the simulated and experimentally measured spectral signals over a range of modulation amplitudes and phases. The presented simulation model offers theoretical support for understanding CW-EPR phenomenon in depth, optimizing experimental parameters, and guiding CW-EPR experiments. It also provides a reference for designing and optimizing EPR systems in subsequent research.
