ABSTRACT:
A wave guide or an assembly of wave guides, characterized in that each wave guide meets the conditions that: 1) at least one of the characteristics of the wave guide is of the same order of magnitude as the largest absolute value of the de Broglie wavelength .lambda..sub.b of a particle or a collectivity of particles moving or able to move through the wave guide; 2) the dimensions of the irregularities of the wall of the wave guide are small with respect to .vertline..lambda..sub.c .vertline., the absolute value of the cutoff wavelength .lambda..sub.c of the wave guide, with the property that for each particle with de Broglie wavelength .lambda..sub.b that moves in the wave guide, holds .vertline..lambda..sub.b .vertline..ltoreq..vertline..lambda..sub.c .vertline.; and 3) .lambda..sub.c has a limited value, and can be found with the aid of the solutions of a relevant wave equation which has been solved by meeting fitting boundary conditions; in that, for the case of photons or luxons, the conditions is met that 4a) the relation between the wavelength .lambda. of the electromagnetic waves and the wavelength .lambda..sub.b of the de Broglie waves, which corresponds with these photons, is given by .lambda.=.lambda..sub.b ; and that, for the case in which the particles are neither photons nor luxons the following conditions are met; 4b) that the energies of these particles are discrete and the physical phenomena in the wave guide and/or caused by the wave guide cannot be described in good approximation without using quantum mechanics, i.e. that the results of these calculations then do not exclusively correspond within 5% with the observations; wherein a characteristic dimension is the distance in between two neighboring pieces of boundary layer, between which a particle or a collectivity of particles can move, when .vertline..PSI..vertline., the absolute value of the wavefunction .PSI. of one particle or a collectivity of particles moving in the wave guide, as a function of the space coordinates, takes an constant value .vertline..PSI..sub.k .vertline..
