  1. Electromagnetic Radiation Powerpoint Templates

  2. Hertz (1857-1894) 1887 (22 years after Maxwell equations) discovered radio waves

  3. Maxwell Equations

  4. Constitutive Equations Vacuum D = εo E B = μo H Conductors J = σ E Linear media D = ε E B = μ H

  5. Non linear media P = χ(1)E + χ(2)E2 + χ(3)E3 + … D = εo(E + χ(1)E + χ(2)E2 + χ(3)E3 + …) D = εo(E + P)

  6. Example SHG

  7. Gauss Theorem Isotropic media => Spherical field

  8. Nº of field lines entering a volume must be equal to the nº of lines living the volume (no magnetic charge accumulation allowed). => Field lines are closed loops.

  9. Stokes Theorem DC current

  10. Free Space

  11. Possible solution: Plane waves

  12. Potentials

  13. Polarization

  14. Refraction & Reflection

  15. Law of reflection: θi = θr Snell’s law: n1sinθi = n2sinθt

  16. Brewster's angle: 56.4º Total reflection: 42º
