Researchers have developed a novel physics-informed neural network (PINN) framework to accurately identify complex eigenfrequencies and reconstruct mode structures for ion-temperature-gradient (ITG) drift waves. This new approach combines Fourier feature encoding, complex-valued feature propagation, and a three-stage training process to overcome challenges posed by localized oscillations and nonlinear couplings in plasma physics. Experiments demonstrate that this framework outperforms existing PINN baselines in recovering target complex eigenfrequencies and two-dimensional mode fields, offering a foundation for analyzing more complex drift-wave modes.
