Reflection and Transmission of Beams at a Dielectric Interface
When complex values are assigned to the source coordinates in the expressions for the fields radiated by a line or point source in a homogeneous medium, the resulting fields have the form of a two-or three-dimensional Gaussian beam. This fact may be utilized to develop results for beam propagation and scattering in inhomogeneous regions from corresponding results for point or line source fields...
متن کاملReflection and Refraction at a Single Interface 5.1 the Behaviour of Light at a Dielectric Interface
The previous Chapters have been concerned with the propagation of waves in empty space or in uniform, homogeneous media. It is now time to introduce more complicated geometries, building towards those appropriate to optical waveguides. We begin with a qualitative discussion of the phenomena that occur when light strikes a dielectric interface. Figure 5.1-1 shows a plane wave incident at an angl...
متن کاملPhase shifts that accompany total internal reflection at a dielectric-dielectric interface.
The absolute, average, and differential phase shifts that p- and s-polarized light experience in total internal reflection (TIR) at the planar interface between two transparent media are considered as functions of the angle of incidence phi. Special angles at which quarter-wave phase shifts are achieved are determined as functions of the relative refractive index N. When the average phase shift...
متن کاملReflection and refraction of an Airy beam at a dielectric interface.
Reflection and refraction of a finite-power Airy beam at the interface between two dielectric media are investigated analytically and numerically. The formulation takes into account the paraxial nature of the optical beams to derive convenient field evolution equations in coordinate frames moving along Snell's refraction and reflection axes. Through numerical simulations, the self-accelerating ...
متن کاملEffect of Interface Roughness on the Reflection Coefficient
All surfaces and interfaces between dissimilar materials are rough. The extent to which this roughness affects the reflection of elastic waves has been the subject of study for many decades. A recent book by Ogilvy [1] provides a comprehensive review and summary of this subject. The problem is of particular interest in ultrasonic nondestructive evaluation. For example, it has been shown that fo...
