Integration Of A Permeable Layer Into Micro Coil Modelling And First Steps Of Automatic Optimization

摘要

Rectangular micro coils which are used in a wide range of applications (e.g. medical or automotive area) are the main components of appropriate wireless transmission systems for frequencies up to 20 MHz. As shown in previous works the self inductance of micro coils has to be maximized to achieve a higher working distance. One possible solution is the usage of a permeable layer underneath the micro coil. The modification of an existing model by use of the magnetic image method and first low frequency results are presented. Another way to increase the performance of micro coil based systems is the optimization of all coil parameters. Algorithms that best fit the demands of automatic model based design optimizations are the so called direct search strategies. Such strategies and first results of an optimization process are presented.
