Microwave and millimeter were computer aided design (CAD) programs currently available do no include the effect of parastic coupling, that is unintended coupling between elements of the circuit not electrically connected. Such coupling can have a significant effect on a circuit's performance as packing densities and frequencies of operation are increased. In this Research Initiation Award, a new method of incorporating parasitic coupling into circuit modeling programs is investigated. The method takes advantage of the weak nature of the coupling (10 to 30 dB) by using a perturbational scheme in which the modifications to the currents in the isolated elements are calculated in a fast, efficient manner. The method promises to improve the speed of existing modeling algorithms significantly, and yet be at least as accurate when realistic roundoff limitations are considered. The algorithm is also speeded up by the development of a uniform, asymptotic expansion of the matrix elements which represent the parasitic coupling. The method will be tested on a number of simple, canonical structures and checked against experimental measurements and results from other available codes.

微波炉和毫米是当前可用的计算机辅助设计（CAD）程序，但不包括帕拉斯特耦合的效果，这是电路元素之间未电的元素之间意想不到的耦合。这种耦合可能会对电路的性能产生重大影响，因为填料密度和操作频率会增加。 在本研究启动奖中，研究了一种将寄生耦合纳入电路建模程序的新方法。 该方法通过使用扰动方案利用耦合的弱性质（10至30 dB），在这种方案中，以快速，有效的方式计算对隔离元素中电流的修改。 该方法有望大大提高现有建模算法的速度，但在考虑实际的圆形限制时至少要准确。 该算法还通过代表寄生耦合的基质元素的均匀，渐近膨胀的发展加速。 该方法将在许多简单的规范结构上进行测试，并根据实验测量和其他可用代码的结果进行检查。
