Abstract. By successive steps
algorithm method the electromagnetic waves of forward and backward directions
propagation in multi-layer limited length structure with periodical nonuniformity
of meander type is investigated. The frequency dependencies of forward and
backward direction wave amplitudes and the transformation of frequency
characteristics by barrier quantity variation are investigated. The amplitude
wave distribution in inner layers of structure is investigated. It is found two
main distributions: sinusoidal and exponential. For large frequency range it is
introduced the definitions of strong and weak nonuniformities and the criterion
of transition between its is found. The frequency dependencies transformation
in large variation interval alignment of layer permittivity is investigated. It
is found the compression of frequency spectrum to its lower limit when this
alignment is increased.
Key words: wave propagation,
multi-layer structure, periodical nonuniformity, frequency spectrum.
