Terminal Configuration Principles for Achieving Various Electromagnetic Integration Units with Flexible Multilayer Foil Technique

Owing to the greater integration capability, flexible multilayer foil (FMLF) technique has a great potential to promote the evolution of passive integration techniques. To understand the mechanism of this technique is essential for its applications and popularization. To this end, this paper reveals the fundamentals and terminal configuration principles to realize various functional electromagnetic integration units with FMLF technique. A regular FMLF winding is taken as the research object, from theoretical analyses on the associated distributed electromagnetic component (DEMC) circuits, the lumped electromagnetic component (LEMC) circuits with different terminal configuration modes are derived. Moreover, A FMLF winding prototype is built for experimental verifications. The LEMC circuits are demonstrated through the comparative analyses between practically measured and LTspice based simulated impedances or port characteristics.
