Single and double layer spiral planar inductors optimisation with the aid of self-organising migrating algorithm

Planar inductors made on a printed circuit boards are rather commonly employed today and there are various software applications to help the designer with their proposal. In this paper we describe the optimisation of a single and double layer spiral inductors made by the help of evolutionary Self-Organizing Migrating Algorithm in order to achieve the required inductance while the resistance of the inductor's conductor was as low as possible. Primarily, these inductors are of large extent, supposed to be utilized at lowfrequency applications such as proximity sensors or metal detectors, but the results stated in this paper can be generalized for various applications. A simple Maple algorithm was also created in order the results gained from the evolutionary algorithm could be verified.
