- fix Coverity error in G4OpBoundaryProcess.cc
13 Aug 15: P. Gumplinger (op-V10-01-04)
- G4OpBoundaryProcess.cc, G4OpRayleigh.cc - checked while loops
3 July 2015 P. Gumplinger (op-V10-01-03)
- Allow for a real and imaginary part of the index of refraction
for Material1 in G4OpBoundaryProcess::GetReflectivity
Bug report: #1762
26 June 2015 P. Gumplinger (op-V10-01-02)
- Correct the reflectivity calculation with complex refractive index;
include the index of refraction of the PreStepPoint medium
Bug report: #1762
23 March 2015 P. Gumplinger (op-V10-01-01)
- change the calculation of NewPolarization in G4OpRayleigh.cc to avoid a
divided by zero when the NewMomentumDirection is perpendicular to the
OldPolarization. If the polarization is perpendicular to the scattering
plane, it will not change after the scattering.
11 March 2015 P. Gumplinger (op-V10-01-00)
- add aParticleChange.ProposeLocalEnergyDeposit(thePhotonMomentum);
to G4OpAbsorption

- Address problem #1675, this requires re engineering of
all UI commands related to optical processes and created
in G4OpticalPhysics.
- Co-working tags: xrays-V10-00-06, op-V10-00-09, phys-ctor-em-V10-00-17
17th October 2014 P. Gumplinger (op-V10-00-08)
- fix G4OpRayleigh.cc to actually set the temperature for materials other
than Water
- G4OpBoundaryProcess: Add a ConstProperty "SURFACEROUGHNESS". If set,
the reflectivity at dielectric_dielectric surface is angular dependent
and calculated from:
exp(-pow((4*pi*theSurfaceroughness*Rindex1*cost1/wavelength),2))
for Rindex1 > Rindex2. Thanks to M. van Dijk (Bristol University).
16th October 2014 P. Gumplinger (op-V10-00-07)
- previous tag was committed only to /include directory
10th October 2014 P. Gumplinger (op-V10-00-06)
- G4OpRayleigh Process: This version calculates the Rayleigh scattering
length for more materials than just Water (although the Water default
is kept). To do this the user would need to specify the
ISOTHERMAL_COMPRESSIBILITY as a material property and optionally an
RS_SCALE_LENGTH (useful for testing). Code comes from Philip Graham
(Queen Mary University of London).

work in situations with parallel worlds
- G4OpBoundaryProcess will now invoke the ProcessHit method of the sensitive
detector associated with the PostStepPoint volume when optical photons are
detected at the entrance boundary
14th June 2013 P. Gumplinger (op-V09-06-05)

http://hypernews.slac.stanford.edu/HyperNews/geant4/get/opticalphotons/509.html
Thanks to Ben Loer (FNAL)
- Add the capability of simulating the transmission of a dichroic filter;
In this first implementation, the photon is either reflected or transmitted
without changing direction. Surface->SetType(dielectric_dichroic);
You must also supply a 2D data file with the format:
4 #ofWavelength-bins #ofIncidentAngle-bins
List of Wavelength-bin values in nm (i)

A dielectric_dielectric surface may now have a wavelength
dependent property "TRANSMITTANCE". If this is specified
for a surface it overwrites the Snell's law's probability.
This allows the simulation of anti-reflective coatings.
Thanks to Evgueni Goudzovski (CERN) for the idea.

G4OpBoundary::PostStepDoIt - all dielectric_dielectric
surfaces may now have a reflectivity <1; not only
'frontpainted' as was the case in the past.
6th May 2009 Peter Gumplinger (op-V09-02-02)
G4OpBoundary::PostStepDoIt now throws an G4Exception
EventMustBeAborted when an invalid surface normal is returnd;
addresses bug report #1060
23th Mar 2009 Peter Gumplinger (op-V09-02-01)
for complex index of refraction: (1)resample the reflectivity
every time in the do-while of DielectricMetal, but don't
re-calculate theFacetNormal (which has already been chosen
in CalculateReflectivity), also (2) avoid an infinite loop by
resetting iTE and iTM inside the do-while of GetReflectivity;
both are bug-fixes.
