Once these modes are known for a given obstacle, the scattering of plane waves incident from arbitrary source directions into arbitrary receiver directions may be evaluated concisely. To support the theory, a method is described for determining characteristic mode currents on thin wires of general ...
Impedance theory has become a favorite method for metasurface design as it allows perfect control of wave properties. However, its functionality is strongly limited by the condition of strict continuity of normal power flow. In this paper, it is shown that acoustic impedance theory can be generali...
A generalized Brewster impedance matching theory is proposed in this paper to overcome the performance degradation of conventional metasurfaces at large incidence angles and achieve ultrawide angular stability. To begin, in the case of transmission, the characteristic impedance of anisotropy metasurface, de...

According to this theory, pathological worry, as in Generalized Anxiety Disorder (GAD), is verbal in nature, negative and abstract, rather than concrete. Neuroimaging studies link the expression of worry to characteristic modes of brain functional connectivity, especially in relation to the amygdala....

His current research interests include modeling, identification, and control of robotic systems (wearable robots), artificial intelligence, and decision-support theory. His current research involved the applications for the functional assisting of dependent people. He was the recipient of the Fellowship ...
According to the homogenization theory, the macroscopic stress is the volumetric average of micro/mesoscale stress field. For granular material, the macroscopic stress is calculated by a formula firstly introduced by Bagi as per(15)σ˜=1Vsym(∑i∈Itii⊗li+∑j∈Otji⊗lj) where sym() ...
