摘要： A left-handed composite material which includes a mixture of a ferromagnetic material and a dielectric material. The direction of magnetization of the ferromagnetic material, and its volume fraction are controlled such that the composite material exhibits negative permeability in a frequency region near the ferromagnetic resonance frequency, and low eddy current losses. Furthermore, the handedness of the material may be locally tuned to be alternately converted into a right-handed material or a left-handed material by application of an external magnetic field, electric field, or mechanical stress. Such materials are easy to make and can be easily scaled up for industrial use.

摘要： Methods and apparatus for detecting an electromagnetic wave are provided. A device for use in an electromagnetic wave detector includes a first device layer having a first contact, a second device layer having a second contact, and a tunnel barrier layer and a resonating magnetic layer formed between the first and second device layers. The resonating magnetic layer produces a spin current responsive to an electromagnetic wave that extends into the first and second device layers. A charge differential present between the first and second contacts is dependent on the spin current.
