The ideality factor ( also called the emissivity factor ) is a fitting parameter that describes how closely the diode's behavior matches that predicted by theory, which assumes the p-n junction of the diode is an infinite plane and no recombination occurs within the space-charge region.

:The reason that it no longer depends on x ( distance ) is that the farther away you are from the infinite plane the more charge you " see ", that extra charge exactly balances the loss of charge force due to distance . talk ) 19 : 20, 24 February 2011 ( UTC)

The SDM starts out with an assumed Floquet / Fourier series solution for all fields, currents and potentials whereas the PMM starts out with a single scatterer, then adds in all of the scatterers in the infinite plane ( in the " spatial " domain ), then uses a transformation to yield the spectral domain representation of the fields.

The stellation of a polyhedron extends the faces of a polyhedron into infinite planes and generates a new polyhedron that is bounded by these planes as faces and the intersections of these planes as edges . " The Fifty Nine Icosahedra " enumerates the stellations of the regular icosahedron, according to a set of rules put forward by J . C . P . Miller, including the "'complete stellation " '.
