The multitrace domain decomposition surface integral equation (MT-DD-SIE) originally developed to analyze electromagnetic scattering from dielectric composite objects is extended efficiently account for perfect electrically conducting (PEC) bodies. This achieved by adopting Robin transmission conditions (RTCs) PEC surfaces. These PEC-RTCs, which are the only governing equations a body, used “co...

This article presents a novel method to accurately simulate electromagnetic scattering at homogeneous polygonal cylinders with arbitrary material properties. A single source equivalence approach is invoked, allowing substitute the background medium for inner of scatterer, provided an equivalent surface current density introduced. We construct pertinent differential admittance operator by means ...

This paper is concerned with the extractions of electromagnetic characteristic modes (CMs) for lossless dielectric bodies, which spurious are prone to generate using traditional definition CMs based on Poggio–Miller–Chang–Harrington–Wu–Tsai (PMCHWT) equations. It found that impedance matrix PMCHWT equations cannot distinguish (i) domain body and background (ii) from excitation source was applie...

Using the membrane analogy, in 1934 Timoshenko derived torsional rigidity of a rectangular prism isotropic material as function its shear modulus, width and thickness. However, he did not consider energy conservation criterion, it could be either unnecessary or replaced by other criteria Timoshenko’s process. To confirm correctness solution, this work re-derives considering all equilibrium cond...

In this paper, we present a novel technique to accurately model scattering phenomena at two-dimensional circular and rectangular structures consisting of arbitrary homogeneous materials, including magnetic media in particular. The proposed formalism utilizes differential surface admittance operator, which invokes single source equivalence theorem replace the inside material by its surrounding m...

Adult attachment classification is traditionally based on qualitative coding of participants’ discourse about their attachment history. Word count-based analyses have proven useful for assessing emotional states from narrative. To expand the understanding of how language is used in emotion regulation processes related to attachment, the authors assess 102 college-aged adults’ language on the Ad...
