Patent ID: 8331135

Claim:
A magnetic device comprising: a plurality of elements of magnetically anisotropic material, neighboring elements of the plurality coupled to each other by a magnetic field; wherein the device is configured to propagate a magnetic signal in a direction from a first element to which an input signal is applied to a last element of the plurality; and one of the elements is of substantially different anisotropy energy from the anisotropy energy attributes of other elements of the plurality; wherein one of the elements is of substantially different anisotropy energy from the anisotropy energy attributes of other elements of the plurality; and wherein the plurality of elements are formed in a first layer, and further comprising: a second plurality of elements of magnetically anisotropic material, the second plurality of elements formed in a second layer displaced from the first layer, neighboring elements of the second plurality coupled to each other by a magnetic field; wherein one of the elements of the first layer and one of the elements of the second layer are coupled by a magnetic field.
