31 // Description: Discrete Process -- reflection/refraction at
32 // optical interfaces
33 // Version: 1.1
34 // Created: 1997-06-18
35 // Modified: 1998-05-25 - Correct parallel component of polarization
36 // (thanks to: Stefano Magni + Giovanni Pieri)
37 // 1998-05-28 - NULL Rindex pointer before reuse
38 // (thanks to: Stefano Magni)
39 // 1998-06-11 - delete *sint1 in oblique reflection
40 // (thanks to: Giovanni Pieri)
41 // 1998-06-19 - move from GetLocalExitNormal() to the new
42 // method: GetLocalExitNormal(&valid) to get
43 // the surface normal in all cases
44 // 1998-11-07 - NULL OpticalSurface pointer before use
45 // comparison not sharp for: std::abs(cost1) < 1.0
46 // remove sin1, sin2 in lines 556,567
47 // (thanks to Stefano Magni)
48 // 1999-10-10 - Accommodate changes done in DoAbsorption by
49 // changing logic in DielectricMetal
50 // 2001-10-18 - avoid Linux (gcc-2.95.2) warning about variables
51 // might be used uninitialized in this function
52 // moved E2_perp, E2_parl and E2_total out of 'if'
53 // 2003-11-27 - Modified line 168-9 to reflect changes made to
54 // G4OpticalSurface class ( by Fan Lei)
55 // 2004-02-02 - Set theStatus = Undefined at start of DoIt
56 // 2005-07-28 - add G4ProcessType to constructor
57 // 2006-11-04 - add capability of calculating the reflectivity
58 // off a metal surface by way of a complex index
59 // of refraction - Thanks to Sehwook Lee and John
60 // Hauptman (Dept. of Physics - Iowa State Univ.)
61 // 2009-11-10 - add capability of simulating surface reflections
62 // with Look-Up-Tables (LUT) containing measured
63 // optical reflectance for a variety of surface
64 // treatments - Thanks to Martin Janecek and
65 // William Moses (Lawrence Berkeley National Lab.)
66 // 2013-06-01 - add the capability of simulating the transmission
67 // of a dichronic filter
