“…где n ′ -коэффициент преломления и n ′′ -коэффициент поглощения. Для нахождения комплексной диэлектрической проницаемости ε использовался алгоритм ее восстановления с помощью вычисления разности между модулями теоретических и экспериментальных частотных зависимостей коэффициентов прохождения и отражения, описанный в [10]. Затем применялся метод наименьших квадратов для минимизации этой разности.…”

The influence of microwave resonance phenomena on complex refractive index in YIG plates has been theoretically and experimentally studied in the frequency range 26–38 GHz. It has been shown that a change in the magnetic field causes severe resonance-type changes in transmission and reflection factors. These changes are due both to effective interaction between millimeter electromagnetic waves and YIG plates (specifically, under ferromagnetic resonance conditions) and to the fulfillment of geometrical resonance conditions (when an integer number of half-waves or an integer odd number of quarter-waves are accommodated on the thickness of the plate). An algorithm to calculate complex refractive index with regard to the tensor-type magnetic permeability of YIG is suggested. The field and frequency dependences of complex refractive index have been analyzed. Geometrical resonance fields have been compared with extrema in the field dependences of the transmission and reflection factor moduli.

A set of ferroelectric and related titanate ceramics and nanocomposites were prepared and their dielectric and electromagnetic properties were studied in a broad frequency range, including microwave, millimeter-wave and THz frequencies. Dielectric and conductivity spectra of the opal-matrix nanocomposites were typical for conductor-dielectric composites and could be described by Cole-Cole relaxations and Drude conductivity. The highest values of microwave dielectric permittivity, losses and conductivity were observed in the composite with Pr 2 Ti 2 O 7 nanoparticles. Absorption properties of ceramic and some composite titanates were measured and estimated in the microwave range. Some of the studied compositions were found to be interesting for development of microwave absorbing or shielding materials.Index Terms-Electromagnetic waveguide, opal matrix, transmission and reflection coefficients, microwave conductivity, dielectric spectra.
