摘要：

We have developed a new permeance meter in the 1MHz - 1.5 GHz range using either a microstrip pickup coil or a shielded loop pickup coil. Both pickup coils and the driving plates are free from LC resonance due to impedance matching. In the MHz range we must consider signal-to-noise ratio of the pickup coil. In the GHz range we must eliminate a voltage induced by electric field, and an electromagnetic higher order mode in a driving plates.
