1 - Open loop
Résumé
Networks can be constructed out of finite open loops. Open loops are guides such that their one-dimensional properties may be considered independent of the open loop shape and radius. Their response function is derived from that of infinite open loops. A general definition of eigenstates is also given. The difference between resonant and force responses is made precise. These open loops have free boundary conditions at their two ends when they are used in network construction. The case of open loops with fixed end conditions is considered also. The photonic analysis is done with the Maxwell electromagnetic propagation wave equation.
