Key Insights

Machine Learning for Surrogate Modeling:
- ANNs are used to build surrogate models that predict the transmission coefficients of metacells based on their dimensions, and vice versa, to optimize metacell designs for desired performance.
Forward and Inverse Design Processes:
- The forward process involves feeding metacell dimensions into an ANN to obtain transmission coefficients, while the inverse process uses desired transmission coefficients to predict the necessary metacell dimensions.
Enhanced Phase-Shift Range:
- The machine-learning-based optimization method significantly increases the phase-shift range of metacells, achieving a -1 dB phase-shift range of 420° compared to the existing solution's 270°.
