This paper presents a comparison between three different topologies of electrically small inductances used in resonant wireless power transmission applications: the coil, the spiral and the ring. Firstly, the product of the coupling coefficient and the quality factor is validated as a good figure of merit for the comparison of different topologies. A(More)
This paper presents a parametric study of wireless power transmission links composed of two identical helical resonators. The effect of the helix radius, the pitch and the number of turns are studied in order to find the optimal geometry that maximizes the transmission efficiency. The product of the coupling coefficient and the quality factor is used as a(More)
Portfolio credit risk models are very often constructed with correlation matrices serving as proxies for interrelations in the creditworthiness of each company. In addition to the size of the matrix, estimation of correlation is also complicated by the fact that defaults are rare and credit-sensitive securities such as stocks, bonds and credit default swaps(More)
