Hello Everybody I want to do the comparison of metals like Silver, Gold, Aluminum, Copper, Sodium and Potassium as plasmonic metals. Now, I am confused about some parameters about what they really mean. 1. what does ε(int) means? Is it better for a plasmonic material to have less ε(int)? 2. What does "Plasma Frequency of a metal in eV" means here? 3. What does ω(int) in eV means? Is it better to have more value of ω(int) in eV to be a better Plasmonic material? 4. What does dumping rate in eV means? How it effect the property of a plasmonic material? 5. What does happen if the light is incident to a plasmonic material below or more than plasmon frequency? Why this plasmon frequency is that so important? 6. In a plasmonic material, the prime target is scattering of light? Why not absorption or transmission? What will be the problem if the light will be either absorbed or transmitted? I will be very much grateful if someone can give my answers. Also, if anyone can suggest any paper or, text book where I can get those answers, I will be really so grateful. Thanks in advance.
