In the real world a dimensional compression is compression along dimensional axis.
Good example of 2-dimentional compression is an architectural arch as itsmembers are compressed under vertical load in both horizontal and vertical directions.
The Flat-Space technology where dimensional compression supposedly can produce trans-dimensional compression, to reduce large object, is a figment of science fiction such as in Ultraviolet by Kurt Wimmer (2006) http://www.whaleofatale.net/iblog/B1015229468/C233882230/E20060305195238/

“Dimensional Compression
Sometimes referred to as Flat-Space technology, Dimensional Compression is used to store objects in a stable pocket dimension. Small objects are stored/retrieved and larger ones systematically deconstructed/reconstructed in a flow of sparkling lights. A significant number of items can be stored for easy retrieval without burdening the user with either weight or size. The technology mainly takes the form of easily overlooked wristbands, although one-inch scabbards holding 42-inch swords are also seen. Handguns, knife-gun hybrids, and ammunition are also hidden in this manner, the bullets flying from the wristbands into the magazines on command.” http://changing-violet.livejournal.com/profile
In short Flat-Space technology can be defined as techno babble.
I hope it helps.

I appreciate your questions as a world citizen. I write them again and try to answer them in the same sequence. 1.) I know that light is both a particle and a wave, but in terms of it's wave properties, what is the correct way to think of light: as a thin, nearly 2 dimensional wave like illustrations show, or does a single light wave extend in all directions like a single sound wave? Also, does a light wave have only one amplitude, or does it vary like with sound waves? All transverse waves are minimum two dimensional, when they travel in a single direction. A longitudinal wave traveling in one direction can be thought of as in one dimension, but they areal;so not especially in case of sound, because rarefactions and compressions are in layers perpendicular to the direction of propagation although the direction in which they get compressed or rarefied is the same as that of propagation. It is not proper to talk of dimensions in such manner in case of waves. when we talk of wave. it may move in many directions or only in one direction. To make life simple let us choose only one direction. Now in a wave some physical quantity changers periodically . that may be in the same direction as the direction in which the disturbance moves or perpendicular to it. Former is called longitudinal and latter transverse. In general except light and other mathematical waves, normals waves are in materials. Light is transverse wave and what vibrates is electrical field and magnetic field perpendicular to electric field and in phase. because the effects of light are mostly describabale by electric field only and magnetic field is always associated with it, we show only one variation and therefore you tried to call it a two dimensional wave. 2.) What is the difference between a particle scattering light and a particle reflecting light diffusely? All phenomena concerning light such as reflection, refraction, dispersions, (even interference, diffraction and polarization are fundamentally scattering and all these are its specail cases in different circumstances and our way of description. when teh reflecting surfce ies not have any periodicity or limited periodicity, reflection is calleddiffuse reflection as it does not follow laws of reflection. 3.) When light is polarized by being reflected, why exactly is it that it is only polarized at/near the Brewster angle? How does this filter out all the other components of light? Simple explanation is that the vibrations of electric vector for reflected wave becomes in teh direction of travel for reflected wave for vibrations in teh plane of incidence. Fo rprpendicular vibrations there i sno such problem. 4.) In diagrams for polarization by reflection that I've seen, it showed only the electric component of light being reflected when it was polarized, is this what really happens? How can it still be light if it's just an electric field? Asociated magnetic field is not shown because maxwell's equations say tht they are inevitably present. 5.) When light passes through a polarizer like sunglasses, what happens to all the light that doesn't get through? Is it absorbed, reflected, and if absorbed, then why don't sunglasses seem to get really hot from absorbing all that light? Probably sun glasses absorb some kind of vibration and should become little hot. There are other kind of polarsers which do not absorb other component but deviates it but those also are ultimatly absorbed by the casing of teh polriser. 6.) What happens to the difference between the light energy absorbed and the light energy emitted by fluorescent materials since they don't seem to get very hot? Fluorescent lights, for example, absorb UV but emit visible light, so what happens to the extra energy? Contribution of light energy absorbed does not contribute to increase of temeperature so substantilly because it does not go to increse the kinetic energy of molecules butincreses tthe ineternal energy of each molecule rather the electronic states in molecules.
