1887 (22 years after Maxwell equations) discovered radio waves


Powerpoint templates

Maxwell Equations


Powerpoint templates

Constitutive Equations

Vacuum

D = εo E

B = μo H

Conductors

J = σ E

Linear media

D = ε E

B = μ H


Powerpoint templates

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)

Gauss Theorem

Isotropic media => Spherical field


Powerpoint templates

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.

Refraction & Reflection


Powerpoint templates

Law of reflection: θi = θr

Snell’s law: n1sinθi = n2sinθt


Powerpoint templates

Brewster's angle: 56.4º

Total reflection: 42º
