Light over ranges

[robinlandseadel at comcast.net]

After finding this official frequency allocation chart:

I started to think of the various charts and graphs that correlate 
color to frequency, though not in the one-for-one correlation 
of the actual frequency (bandwidth?) of the color, but assigning 
that color to a different frequency, and wondering what sorts of 
things I'd find if I googled "Light over Ranges", which led in a 
rather direct fashion to:

                   Abstract. A method is described for obtaining the 
                   azimuth and ellipticity of polychromatic elliptically 
                   polarised light as a function of wavelength, without 
                   the need for wavelength scanning. Elliptically 
                   polarised light with calculable polarisation was 
                   generated using a birefringent plate or a twisted 
                   nematic liquid crystal cell, and measurements of the 
                   azimuth and ellipticity of the light were made using 
                   the method. Good agreement with the calculated 
                   values was found, thus demonstrating the correctness 
                   of the technique.

Although I lack the technical know-how to decipher this abstract,
its clear that there's many technical terms and concepts in this
abstract that correlate to AtD. Looking further there's:

                   The dielectric omnidirectional reflector consists of 
                   multilayer films, and has potential applications in 
                   solar and thermoelectric power sources and laser 
                   microcavities. . . .

                   . . . .The MIT reflector, described in Science, vol 282, 
                   p1679, was constructed as a stack of nine alternating 
                   layers of polystyrene and tellurium, and demonstrates 
                   omnidirectional reflection over the wavelength range 
                   from 10 to 15 micro m. Because the omnidirectionality 
                   criterion is general, it can be used to design reflectors 
                   in many frequency ranges.

Just thinking how this ties to "Gravity's Rainbow", remembering
the periodic table of the elements from my 7th/8th grade science
class. I'd look at that periodic table, noting that many of these tables 
were (like Slothrop's map of amourous conquests in London) 
color-coded:

And, of course, the era of AtD is, among other things, is the time 
when scientists started to think of matter and light in describable,
predictable, calculable terms, as a range of frequencies.
