Profile height parameter

The physical parameters of the waveguide and the free-space wavelength A of the source of excitation are contained in the waveguide parameter V and the profile height parameter A defined inside the back cover. 

Conversely, in the above example, the variation of the phase change with polarization of the plane wave electric field is small when the difference between and ng is small, although the incident wave is still totally reflected. Thus, if the refractive indices are nearly equal, the slight nonuniformity maintains total internal reflection, but the medium is virtually homogeneous as far as polarization effects are concerned. Further, the fields associated with plane-wave reflection satisfy the scalar wave equation, as discussed in Section 35-6. With this perspective, we anticipate that waveguides of arbitrary refractive-index profile have some analogous simplification in the description of their modal fields, provided only that the profile height parameter is small, i.e. A < 1, or n,. ... 

The analysis for finding rg and p is facilitated by working with the fiber and modal parameters Vand U, since both are dimensionless and U is independent of the profile height parameter A. We substitute Eq. (15-2) and the profile... 

The peaks are defined by the parameters A the peak height, W- the width of the peak at half height, and P-t the peak position f- is the profile function parameter,which can vary between -0.5 and 1.0 for sensible profiles and effectively describes the tail region of the profile (j). The scatter from disordered molecules in the fibre is considered to have the polynomial form...

The self-constructed Laserphoto Sedimentometer and the measuring procedures to obtain the transmission-height profiles and the characterizing parameters for the turbidity and the hindered sedimentation behaviour of the flocculated suspension are described in earlier publications (10,1). Thus only a summary of these parameters is given here ... 

The Britter-McQuaid model is a dimensional analysis technique, based on a correlation developed from experimental data. However, the model is based only on data from flat rural terrain and is applicable only to these types of releases. The model is also unable to account for the effects of parameters such as release height, ground roughness, and wind speed profiles.
