COMPOSITE ON THE BASIS OF MICROWIRE WITH NEGATIVE VALUE OF PERMEABILITY IN MICROWAVE RANGE OF FREQUENCIES

The composite of an amorphous microwire with negative value of permeability in a high frequency and super high frequency range of the electromagnetic field is examined. The case when dielectric permeability may be also negative is separately analyzed. Now the composite materials, simulating negative values of the real part of dielectric permeability – Re [ε] = ε ′and magnetic permeability – Re [µ] = µ ′ are created, with the help of structure elements such as rectilinear pieces of conductors and sectors of circles [1]. The information on the given subjects, and also about some opportunities of application of the given materials is possible to read in [2]. In this work the opportunity of using of magnetic amorphous cast microwires of the certain alloys for creation of a composite with negative value of µ ′ and an opportunity of creation of a composite with simultaneously negative values of permeability µ ′ and ε ′ is examined. 1. The abnormal area of a dispersion – Re [µ] = µ ′ usually is in the area of strong absorption, when Im [µ] = µ′ ′ is great. If for some reasons negative value µ ′ leaves the area of absorption, the electromagnetic wave is completely reflected from such medium in a range of frequencies where µ ′ is negative. That connects the equation for a wave vector k
