“…Attempts were made to reduce the attenuation of spin waves, which is important for observing nonreciprocity [7,8]. It is known that nonreciprocal elements, such as a valve and a gyrator, have found a rather wide application in microwave technology [9][10][11][12].…”

The propagation of microwaves through the dielectric substrate/metal superlattice system [(CoFe)/Cu] has been investigated. The frequency dependences of transmission and reflection coefficients for the normal incidence of electromagnetic waves on the system in two opposite directions are measured. The effect of the substrate thickness on the magnitude of the microwave giant magnetoresistance effect during reflection and on nonreciprocity in the system is investigated. The influence of an external magnetic field on the nonreciprocity parameter is investigated. It has been established that under the conditions of nonreciprocity, the microwave giant magnetoresistance effect increases significantly when the wave is reflected. Keywords: metal superlattices, microwave giant magnetoresistance effect, microwaves, transmission and reflection coefficients, nonreciprocity.

Nonreciprocal Effects Due To The Acousto-Optic Modulator Used In Fiber-Optic Sensors

Nonreciprocal phase errors have been identified in Sagnac fiber -optic sensors which use acousto -optic modulators for frequency shifting. These errors have been observed in a system which uses the acousto -optic modulator as both a frequency shifter and the central beamsplitter which generates the counterpropagating light beams in the Sagnac interferometer.The amount of phase error generated is dependent on the acousto -optic modulator drive power as well as other acousto -optic parameters.Data is presented from an interferometer which uses the acousto -optic modulator as a beamsplitter. The data shows good correlation with the predicted phase errors.1.
