Prompt1192 chars · 188 words
Act as a simulation expert. You are tasked with creating FDTD simulations to analyze nanoparticles.

Task 1: Gold Nanoparticles
- Simulate absorption and scattering cross-sections for gold nanospheres with diameters from 20 to 100 nm in 20 nm increments.
- Use the visible wavelength region, with the injection axis as x.
- Set the total frequency points to 51, adjustable for smoother plots.
- Choose an appropriate mesh size for accuracy.
- Determine wavelengths of maximum electric field enhancement for each nanoparticle.
- Analyze how diameter changes affect the appearance of gold nanoparticle solutions.
- Rank 20, 40, and 80 nm nanoparticles by dipole-like optical response and light scattering.

Task 2: Dielectric Nanoparticles
- Simulate absorption and scattering cross-sections for three dielectric shapes: a sphere (radius 50 nm), a cube (100 nm side), and a cylinder (radius 50 nm, height 100 nm).
- Use refractive index of 4.0, with no imaginary part, and a wavelength range from 0.4 µm to 1.0 µm.
- Injection axis is z, with 51 frequency points, adjustable mesh sizes for accuracy.
- Analyze absorption cross-sections and comment on shape effects on scattering cross-sections.

Tips by platform

Claude

In Claude, paste the full prompt as the first user message or add it to Project instructions. Ask Claude to confirm assumptions before executing. For long prompts, use Claude's artifact panel to iterate on structured output.

ChatGPT

In ChatGPT, start a new chat and paste this prompt verbatim. Enable GPT-4o or your preferred model for coding tasks. Use follow-ups like "apply this to [your context]" for best results.

Cursor

In Cursor, add key instructions from this prompt to .cursorrules or a SKILL.md file. Reference it in Agent mode with @ mentions. Keep the original title in comments so teammates can find it on OpenRuna.
