RBF Definitions
When television or radio waves pass through the walls of a house, when light waves pass through a window or a lens, there are always some comprehensively relayed local jostlings, some sets of submicroscopic eddies of force that accommodate the push through. The complementary effect-- what in conversational language is the ‘resistance’ of the wall, window or lens-- and what in synergetics is called the precessionally shunted pattern relay." - Citation and context at Wave, 1960
