Classical optics is divided into two main branches: geometrical (or ray) optics and physical (or wave) optics. In geometrical optics, light is considered to travel in straight lines, while in physical optics, light is considered as an electromagnetic wave. Geometrical optics can be viewed as an approximation of physical optics that … Web(1) $$ I = \frac {I_0} {2} $$ For linearly polarized light with intensity I 0, the intensity transmitted through an ideal polarizer, I, can be described by Malus’ law, (2) $$ I = I_0 \cos ^2 {\theta} $$ Where θ is the angle between the incident linear polarization and …

The progress in nano-fabrication [24] allows one to make optical components that are subwavelength as the wavelength of blue light is about 450 nm. As a result, interaction of light with nano-scale optical components requires the solution of Maxwell’s equations in its full glory.
WebDiffraction is defined as the interference or bending of waves around the corners of an obstacle or through an aperture into the region of geometrical shadow of the obstacle/aperture. The diffracting object or aperture effectively becomes a secondary source of the propagating wave. Italian scientist Francesco Maria Grimaldi coined the …
