Regimes of coupling: from core-shell particle to dimer, Motivation (What…

- - - - We use 2D optical theorem to obtain scattering cross-section
      - Scattered amplitudes
        
        We use MST
        
        We have verified validity of our method by comparison to FEM
        
        MST uses re-decomposition of scattered fields
        
        Hankel-Hankel decomposition is a new idea
        
        Mie problem may be formulated
        
        generalized Lorentz-Mie theory
    - - One-nested cylinders can be described with MTMM
        
        MTMM is basically a TMM with a decomposition matrix (bessel-bessel + hankel-hankel)
    - - On the figure, we observe Strong-to-weak couping transition
        
        Then after nesting the rods peak splitting transition continues to occur smoothly
        
        d = 0 is the core-shell particle regime. Something about its dipole resonance?
      - Acknowledgement: see PRA
  - - - We study scattering spectra as the distance decreases, to the point where rods touch, and even smaller, when the smaller rod is embedded into the larger one.
        
        We study nested rods
- - - - Dimers: what is known?
        
        Hybridization of modes
        
        We pull core out of shell to make a dimer
    - - Nested cylinders: what is known?
        
        Scattering cancellation and invisibility [review: Alu: Adv. Mat.]
