Greptile Summary

This PR adds comprehensive documentation for new microwave components introduced with the mode impedance feature. The changes include four new RST documentation files that document transmission line mode analysis, path integral specifications, impedance calculator functionality, and microwave output data containers. These additions extend the existing microwave documentation to cover the new MicrowaveModeSpec, ImpedanceCalculator, and related data structures that enable automatic characteristic impedance calculation for transmission lines. The documentation follows established RST formatting conventions with proper autosummary blocks, code examples, and cross-references. Additionally, the microwave index file is updated to integrate these new sections into the overall documentation structure, maintaining consistency with the existing documentation patterns in the Tidy3D codebase.

Important Files Changed

Changed Files

Filename	Score	Overview
docs/api/microwave/path_integrals.rst	5/5	New comprehensive documentation for path integral specifications used in microwave impedance calculations
docs/api/microwave/impedance_calculator.rst	5/5	New documentation for the ImpedanceCalculator class and path integral execution functionality
docs/api/microwave/mode_solver.rst	5/5	New documentation for MicrowaveModeSpec and transmission line mode analysis capabilities
docs/api/microwave/index.rst	5/5	Updated index to integrate four new microwave documentation sections into the overall structure
docs/api/microwave/output_data.rst	4/5	New documentation for microwave data containers with minor issues in code examples

Confidence score: 5/5

• This PR is safe to merge with minimal risk as it only adds documentation files without modifying any core functionality
• Score reflects comprehensive documentation coverage, proper RST formatting, and adherence to established documentation patterns
• Pay close attention to docs/api/microwave/output_data.rst which has minor undefined variable issues in code examples

logic: num_modes is undefined in this code example. Define it beforehand or use a specific number like range(2).
