Chaos generators based on yttrium-iron garnet films for communication systems with a chaotic synchronous response.

This Letter reports the development of a directly chaotic communication system, in which chaos generators are used that are based on yttrium-iron garnet (YIG) films. YIG-based chaos generators provide a stable chaotic synchronous response and almost ideal masking of the signal with high communication reliability and quality. Characteristics of these generators are compared with conventional chaos generators. [ABSTRACT FROM AUTHOR]
