Thanks. I'm glad you find it useful to you. Best of luck for your exam.

By MM I'm guessing you're referring to the Method of Moments (MoM). By definition it is computational method as it solves Electromagnetic problems using mathematical methods. Now I'm not to understand what you mean by "method based on pure coding without any reliance on simulation"". Any computational method will be coded using mathematical methods to run on a computer. By definition any method that will run on a computer is a computer simulation. Now if you're referring to Analytical models, the only pure analytical solution of Maxwell's equation will be Mie theory but it is limited to spheres. Anything deviating from a sphere in a uniform medium will require computation simulations.

Retardation effect is due to the time it takes for light to travel. If you imagine a sinusoidal wave passing onto a NP, the electrons on one side may experience an electric field pointing upward at a time t, while the electrons on the other side will experience the same field a later time because the wave it takes time for light to travel from one side to another. Even if this time is very short it's not instantaneous.

These maps are not obtained experimentally. There are obtained from theory/simulation. There is no experimental optical setup that would allow you to map the spatial distribution of em waves inside a material (substrate). A SNOM (Sanning Near field Optical Microscope) can be used to map out the evanescent fields at the surface of the substrate.

@@nicolaslarge8622 Okay, thank you.

Thanks. This is a great suggestion. I've just added a link to the lecture notes for all the videos.

No, they are not unit vectors. They are the complex vector fields.

If you were to focus only on plasmonics, I would recommend going though Ch. 1 (intro), 2 (electrodynamics), 4 (Optical Interactions), 7 (numerical methods), 8-9 (plasmonics). Chapters 10-14 are more related to specific applications of Plasmonics.

That is partly correct. The generalized model (Drude-Lorentz-Sommerfield model) describe an harmonic oscillator with restoring force. This is the more rigorous description of the electron gas oscillation as these electrons do experience the Coulomb attraction from the ion background. However, because the electrons are only weakly bound to the nuclei, this Coulomb attraction can be neglected and the model reduce to a simple Drude-Sommerfeld model, which indeed contains no restoring force. The Lorentz model is later introduced to account for the Interband transitions (25:25). So as you can see it does not only apply to dielectric materials. Hope this clarifies.

Yes, the whole course will remain online. Take all the time you need to go through.

Thanks

This course is not associated with a single textbook but it does mostly follow the structure of "Principles of Nano-Optics" by Novotny and Hecht.

Thanks. I'm Glad you liked it.

Hi Nicolas. Thank you for the detailed information! Liked your way of explaining things.
