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...

We present a method to enhance the accuracy of platform-based, high-frequency (HF) direction-finding (DF) systems using dynamic mode selection. To improve bandwidth and efficiency, metallic platform supporting DF array is used as primary radiator by employing electrically small antennas excite linearly independent combinations its characteristic modes (CMs). However, radiation characteristics t...

This article provides a comprehensive review of recent applications characteristic mode analysis (CMA) to innovative antenna element designs, including multiport, circularly polarized, wideband, reconfigurable, and dielectric resonator antennas (DRAs). Emphasis is placed on the interpretation modes (CMs) for those unfamiliar with method physical insights gained from eigenvalues eigenvectors an ...

Within the finite element framework, we deal with large-scale eigenvalue problems induced by free vibration analysis of complex structures. The classical approach for the solution of such problems consists first of reducing the number of unknowns, allowing to reduce the computational cost of eigensolver, because only the lowest eigenfrequencies are classically researched in modal analysis. Comp...

Background: Human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) have emerged as a promising experimental tool for translational heart research and drug development. However, their usability as a human adult cardiomyocyte model is limited by their functional immaturity. Our aim is to analyse quantitatively those characteristics and how they differ from adult CMs. Methods and R...

BACKGROUND AND PURPOSE Restriction spectrum imaging is a sensitive DWI technique for probing separable water diffusion compartments in tissues. Here, we evaluate RSI-CMs derived from the spherically-restricted water compartment for improved tumor conspicuity and delineation from nontumor tissue and reduced sensitivity to edema compared with high-b-value DWI and ADC. MATERIALS AND METHODS RSI ...

The existing methods for calculating electromagnetic scattering can be used to obtain the RCS of power lines. However, these do not take advantage periodicity We propose a fast calculation method combining integral equation discontinuous Galerkin (IEDG) and characteristic modes-Sherman–Morrison–Woodbury algorithm (CM-SMWA) exploiting lines with stranded structure. adopt IEDG discretize electric...

During the past decade, many corporations world-wide have embraced hybrid training programmes to derive benefits of the conventional face-to-face (F2F) learning environment coupled with those of online learning environment for their employees. A majority of researches on hybrid learning focus upon blending of existing F2F programmes of brick ‘n’ mortar institutions with online component. This p...
