v1.1.0

tmmax v1.1.0 Release Notes

New Features and Enhancements

1. JIT Decorator to Vectorized TMM

• Implemented a optimized Transfer Matrix Method (TMM) using JAX, enabling just-in-time (JIT) compilation.

2. Material Database

• Includes 29 commonly used optical thin-film materials.
• Provides refractive index (n) and extinction coefficient (k) data in .npy format for faster loading.
• Source references available in docs/database_info.

3. Advanced Thin-Film Optical Property Calculations

• Computes reflection (R), transmission (T), and absorption (A) spectra for both coherent and incoherent multilayer structures.
• Supports flexible configuration of layer coherency.

4. Optimized Data Handling

• Switched from CSV to .npy format for material data, reducing data loading time.
• Example functions available for visualizing material properties.

5. Documentation and Example Gallery

• Provides step-by-step examples for material retrieval, optical property calculations, and filter design.
• Example use cases include anti-reflective coatings, high-reflectivity mirrors, and bandpass filters.

6. Performance Benchmarks

• Benchmarked against other TMM implementations (tmm, tmm-fast, vtmm).
• Demonstrates good scalability, particularly for deep multilayer stacks.

Future Plans

• Expand the material database with additional optical thin-film materials.
• Improve benchmarks with newer releases of comparison libraries, also add GPU benchmarks.
• Enhance inverse design capabilities with more advanced optimization techniques.
