Tight Focusing of Light Beams: Effect of Polarization, Phase, and Coherence
Tight Focusing Light Beams Effect of Polarization Phase Coherence
2013/7/3
The focusing theory of electromagnetic waves has been well developed. A scalar wave theory satisfactorily describes the focusing process for a small semi-aperture angle. However, the vectorial charact...
