Abstract: The disclosure provides an electromagnetic device design system including: one or more processors of a machine; and computer-storage medium storing instructions, which when executed by the machine, cause the machine to perform operations for EM sensitivity analysis for an electromagnetic (EM) device. The operations include: initiating physical parameters of the EM device, wherein the EM device comprises multiple ports; performing EM simulation for the EM device at a pre-solution frequency using the finite-element method (FEM); applying single-size matrix Padé via Lanczos (MPVL) method in fast frequency sweep and performing EM simulation for the EM device under excitation at each port to obtain field solution of the EM device at frequencies in a frequency range; calculating S-parameters for the multiple ports of the EM device; and calculating derivatives of the S-parameters with respect to one of the physical parameters in the frequency range.

Abstract: A datacenter network can be made of points of deliveries and patch panels. Rewiring the logical links within the datacenter network to meet a new network topology is computationally intense. Methods, systems, and apparatuses are provided to modify an existing network topology with a provided existing physical topology and logical topology into the new network topology. For example, the provided physical topology can include changes to the network, such as adding new points of delivery, adding additional patch panels, increasing the number of physical connections between points of delivery and patch panels, or removing a point of delivery.
