An Analytical Approach for Material Synthesis Based on Shielding Effectiveness Characteristics

Öz

We
describe an analytical method to synthesize a Debye-like equivalent homogeneous
material by computing the associated parameters such as static relative
permittivity, relative high-frequency limit permittivity, relaxation time, and
the width of the material for a given shielding effectiveness specification and
a given range of frequency as well as material width. We illustrate the
parameter extraction procedure with a numerical example, in which we validate
that the applied method is able to produce the desired SE profile within the
specified frequency range.
