Apr 1, 2025April 2025: Implemented Material Library Pretty Printing and Concise Material Summaries in flexcompute/tidy3d to improve readability and rapid assessment of materials, variants, and the library. Using rich.print, named mediums are displayed by their names for brevity, and materials/variants now provide concise summaries for quick review. This enhancement reduces review time, accelerates material evaluation during design and QA, and strengthens the deliverable's UX. The work is supported by a frontend-oriented commit and aligns with the team’s UX and maintainability goals.

Feb 1, 2025February 2025: Concentrated on expanding visualization capabilities and tightening adjoint simulation correctness in flexcompute/tidy3d. Delivered broader plotting support by introducing viz_spec to AbstractStructure for structures without a defined medium, supported by a new test to verify plotting does not fail when the medium is undefined. Fixed adjoint data construction to derive sources only from traced fields, eliminating reliance on untraced data and improving the reliability and accuracy of adjoint simulations. These changes reduce validation risk, accelerate design exploration, and strengthen regression coverage. Technologies demonstrated include Python, autograd workflows, and test-driven development with explicit commit traces.
