Electromagnetic device

摘要

An electromagnetic device comprising solid matrix layer, wherein micro-capsules containing suspension anisotropic particles are dispersed, and a means for applying electric field or magnetic field to the anisotropic particles. According to the present invention, not only range of transmittance of solar radiation can be much improved, but also a smart window of large scale having nonuniformity of thickness and nonuniformity of density of particles can be realized.
