A photo‐crosslinking cinnamic acid‐modified starch (CA‐St) copolymer is synthesized through an esterification reaction using 4‐dimethylaminopyridine and 1‐(3‐dimethylaminopropyl)‐3‐ethylcarbodiimide as catalysts. The structure of the CA‐St is confirmed by 1H nuclear magnetic resonance and infrared spectroscopy. Using the nanoprecipitation method, the photo‐crosslinking CA‐St copolymer is aggregated...
Iterative solution of the electric-field integral-equation (EFIE) faces redundant computations for the multiple right-hand-side (RHS) problems. An efficient direct solver of the EFIE based on hierarchically compressed matrix algorithm is developed to deal with multiple RHSs. The multilevel UV method is employed to construct a hierarchically compressed matrix. Exploiting the symmetry of EFIE system...
In this paper, a set of higher-order hierarchical divergence-conforming vector basis functions based on curved triangular patches is presented for EM scattering analysis of PEC objects above a lossy half space. Numerical examples are presented to demonstrate the valid and efficiency of the proposed approach.
In this paper, an efficient numerical technique is presented for analyzing the reflection and transmission characteristics of planar finite frequency selective surfaces (FSS) structures with multilayered dielectric substrate. For ideal infinite size FSS structures, only one single unit cell is of interest with the help of Floquet's theorem and periodic Green's functions. However, for FSS structures...
In this paper, an efficient numerical approach is proposed for analyzing the scattering from PEC objects above a lossy half space over wide angular and frequency band. One of the principal tools for the analysis of scattering from targets located in half-space is the method of moments (MoM) and the half-space multilevel fast multipole algorithm (MLFMA). Since the surface current and the scattered...
An efficient surface integral equation solution is presented to the problem of electromagnetic scattering from chiral material coated conducting object above a lossy half space. By using the surface equivalence principle and the Bohren decomposition scheme, the electric-magnetic current combined-field integral equation (JMCFIE) combined with the combined-field integral equation (CFIE) is developed...
For the fast design of microwave circuit, an unconditionally stable and fully explicit finite-element time-domain (FETD) method is presented. The Crank-Nicolson (CN) scheme is implemented leading to an unconditionally stable mixed FETD method. A hierarchical (H-) matrix algorithm is introduced to provide a data-sparse way to approximate the inverse of the sparse system matrix produced by the CN-FETD...
Background IgG4-TIN is the most common pattern of renal involvement in IgG4-related disease. There are several proposed diagnostic criteria of IgG4-TIN recently. Two of them proposed by the Mayo Clinic and JSN are predominant. However, histopathological criteria of the number of IgG4+ plasma cells and several histological features are still under discussion due to low amount of tissue in renal biopsy...
A full-wave analysis for the transmission characteristic of finite planar frequency selective surface (FSS) is presented using the method of moment (MoM) with the layered medium Green's functions. A fast numerical approach, the multilevel UV method, is employed to speed up the MoM solution. Finally, numerical results show the good performance of the approach, and its accuracy is verified by the agreement...
