TL;DR: A review and critique of different laminate theories used for the modeling and analysis of laminated composite beams or plate structures is presented in this paper, where a 3D complete field solution for active laminates based on a modal, Fourier series solution approach is used to compute all the throughthickness electromechanical fields near the dominant resonance frequency of a beam plate with two piezoelectric (sensor and actuator) and one structural layers.

TL;DR: In this article, the electromagnetic properties of general classes of materials can be obtained by inverting the measured or numerically simulated reflection (S 11) and transmission (S 21) coefficients through a known thickness of a planar slab of the material.

TL;DR: A multiple scattering theory for elastic wave propagation in a discrete random medium is presented in this article, where a selfconsistent multiple scattering formalism using the T matrix of a single scatterer in conjunction with the quasicrystalline approximation (QCA) and a self-consistent pair correlation function is employed to study the phase velocity and coherent attenuation of elastic waves by a random distribution of cavities and elastic inclusions embedded in an elastic matrix.

TL;DR: In this article, the effect of substrate properties on the effective properties of a metamaterial slab was studied and both simulation results and measurement data for a specific split-ring resonator structure for two different substrate thicknesses were presented.

TL;DR: In this article, the first direct measurements of the material properties e, μ, and β for microwave chiral composite materials prepared in a laboratory in the frequency range of 8-40 GHz were presented.
