## Description

This MCP server provides precise calculations for Surface Plasmon Resonance (SPR) in metallic nanoparticles using Mie theory approximations. It allows AI agents to determine the resonance wavelength, extinction coefficients (including absorption and scattering contributions), and electric field enhancement factors based on particle material, size, shape, and the surrounding medium's refractive index. Use `get_resonance_wavelength` to find peak wavelengths, `get_extinction_coefficient` for light attenuation, `get_field_enhancement` for surface field concentration, and `compare_material_performance` to evaluate different metals under identical conditions.

## Frequently Asked Questions

**What materials are supported for calculation?**
The calculator supports noble metals like gold and silver, as well as transition metals such as copper and aluminum.

**How do I calculate the resonance for a nanorod?**
To calculate for a rod, use the `get_resonance_wavelength` tool and ensure you provide the `aspectRatio` parameter.

**Can I compare different metals at once?**
Yes, you can use the `compare_material_performance` tool to evaluate multiple metals simultaneously under the same physical parameters.
