  4.  Nanoparticle optics
  5.  Applications: Optical biosensing, plasmonic waveguides, optical antenna, surface enhanced Raman scattering (SERS)
  6.  Light transmission through nanoscale apertures (extraordinary transmission effects)
  7.  Metamaterials: Negative refractive index and super-lens
  8.  Hands-on computer simulations: SPR phenomena and light transmission through nano-apertures
 
Prerequisites: Basic knowledge of Maxwell’s equations
 
Grading: 60% homework, 40% final presentation
