Abstract
This paper proves the generalized Foster theorem, which can be applied to any lossy situation, while the original Foster theorem [1] only applied to reactive termination. Furthermore, the formula of Q with network parameters is described. One example, the quality factor Q of a passβthrough resonant cavity, is given here. It is clearly seen that the slope of the reactance function may be negative in a lossy situation. Β© 2003 Wiley Periodicals, Inc.

For an n-dimensional simplex in E", we establish a sine theorem and some inequalities for k-order vertex angles which are defined in this paper. To prove these results. we give a formula about the inverse matrix of the metric matrix of an n-parallelotope.
The formal relationships between the scalar and tensorial virials and Eshelby tensors have been presently investigated. The key idea is to evaluate the Eshelby stress from discrete or atomistic simulations for a structured body, conceived as a numerical homogenization method to reconstitute the macr
An edge-scheduled network N is a multigraph G = (V, E), where each edge e E E has been assigned two real weights: a start time a(e) and a finish time p(e). Such a multigraph models a communication or transportation network. A multiedge joining vertices u and v represents a direct communication (tran
