Abstract

In the coupling arrangement, there are striplines of variable width and thin magnetic film elements of elongated shape. This results in an improvement of signal energy transfer from a controlling to a controlled thin magnetic film element.

Coupling Arrangement

In the coupling arrangement, there are striplines of variable width and thin magnetic film elements of elongated shape. This results in an improvement of signal energy transfer from a controlling to a controlled thin magnetic film element.

The two thin magnetic film elements 1 and 2 are of rectangular shape. A is the long side, B is the short side and D is the thickness. The film elements are displaced with respect to each other by about 90 degrees. They are coupled by a closed stripline loop 3. The latter's width is adjusted to the relative measurements of the thin film elements. The transmutation from the small to the wide part takes place continuously. The distance ratio W1: W2 between forward and return conductors of the stripline equals the ratio B: A of the stripline widths at the location of the respective magnetic film elements.

By applying the orthogonal driving method for the magnetic film elements and by choosing for example A: B = 3: 1, the control effect from the controlling to the controlled magnetic film element is about three times greater. This is when element 1 acts as the controlling and element 2 as the controlled element rather than if element 2 acts as the controlling and element 1 as the controlled element.

Information transfer devices comprising components of such structure exhibit intrinsic non-reciprocal transfer properties so that backflow of information is avoided. Therefore, as far as the transmission of binary in...
