An Electromagnetism electromagnetic cavity is a cavity that acts as a container for electromagnetic field s such as photon s, in effect containing their wave function inside. The size of the cavity determines the maximum photon wave length that can be trapped. Additionally, it produces quantized energy level s for trapped charged particles like electrons and protons . The earth s magnetic field in effect places the earth in an electromagnetic cavity. Physical description of electromagnetic cavities Electromagnetic cavities are represented by potential well s, also called boxes , which can be of limited or unlimited depth V sub 0 sub . Quantum mechanic boxes are described by the time independent Schr dinger equation div align center math left frac hbar 2 2m nabla 2 V mathbf r right psi mathbf r E psi mathbf r math div with the additional boundary condition s the wave function is confined to the box infinite deep potential well or approaches zero as the distance from the wall increases to infinity, thus normalisable the wave function must be continuous function continuous the derivative of the wave function must be continuous which leads to real solutions for the wave functions if the net energy of the particle is negative., i.e. if the particle is in a bound state . Applications of electromagnetic cavities Electrons which are trapped in an electromagnetic cavity are in a bound state and thus organise themselves as they do in a regular atom , thus expressing chemical like behaviour. Several researchers have proposed to develop programmable matter by varying the number of trapped electrons in those cavities. http www.wired.com wired archive 9.10 atoms.html The discrete energy levels of electromagnetic cavities are exploited to produce photons of desired frequencies and thus are essential for nano or submicrometre scale laser devices.
