Abstract： |
This invention relates to a negative permeability device with tunable temperature based on ferroelectric ceramic particles, in which, said device is composed of multiple laminated teflon templates, ferroelectric ceramic particles and a temperature-controlled device, in which, a hole-array is set on each of the teflon template inserted with the particles, said device can drive elctromagnetic waves to generate strong magnetic resonance at a certain band and includes isotropical negative permeability effect adjacent to the magnetic resonance to utilize the adjustment character of temperature to dielectric constant of the particles to control its negative permeability. |
