The invention discloses a device for testing the
membrane complex permeability with the short-circuit micro-strip line method, and belongs to the technical field of magnetic material testing.The device comprises a base, an
outer coil, an inner coil, a carrying platform and a short-circuit micro-strip line clamp.The
outer coil and the inner coil are coaxial
hollow cylinder coils, the inner coil is located inside the
outer coil, the outer coil is arranged on the base, the carrying platform is arranged on the inner side of the inner coil, the short-circuit micro-strip line clamp is placed on the carrying platform, and an included
angle alpha is formed between the outer coil, a center shaft of the inner coil and the carrying platform and the horizontal plane.According to the device, a center
magnetic field is formed through two coaxial
hollow cylinder coils, an
electromagnet is not required, the size is small, the weight is light, power dissipation is low, a large center
magnetic field can be achieved through small coils, and cost is low; the whole testing
system is not replaced when the coils are damaged, the corresponding-part coil is only need to be replaced, use is convenient, and working
voltage is low.
