Photon The photon is massless‚[Note 2] has no electric charge‚[12] and is stable. A photon has two possible polarization states and is described by exactly three continuous parameters: the components of its wave vector‚ which determine its wavelength λ and its direction of propagation. The photon is the gauge boson for electromagnetism‚[13] and therefore all other quantum numbers of the photon (such as lepton number‚ baryon number‚ and flavour quantum numbers) are zero.[14] Photons are emitted

INTRODUCTION TO F MICROWAVE ENGINEERING Modern electromagnetic theory was formulated in 1873 by James Clerk Maxwell solely from mathematical considerations. Maxwell’s formulation was cast in its modern form by Oliver Heaviside‚ during the period 1885 to 1887.Heinrich Hertz‚ a German professor of physics understood the theory published by Maxwell‚ carried out a set of experiments during 1887-1891 that completely validated Maxwell’s theory of electromagnetic waves. It was only in the 1940’s (World War
