TL;DR: In this article, the electromagnetic isolation and coupling characteristics of basic structures, namely metal pads, spiral inductors, and spiral transistors, implemented in a core-logic CMOS process are evaluated and modeled.
Abstract: The electromagnetic isolation and coupling characteristics of basic structures, namely metal pads, spiral inductors, and spiral-transistors, implemented in a core-logic CMOS process are evaluated and modeled. The models provide design guidelines on the isolation characteristics of guard-rings and shield layers for RF cross-talk suppression between circuit blocks. The importance of electromagnetic coupling to layout interconnects is demonstrated.

TL;DR: In this article, the equivalence of propagation characteristics for the transmission line matrix (TLM) and finite-difference-time-domain (FD-TD) methods in two dimensions is discussed.
Abstract: The equivalence of propagation characteristics for the transmission line matrix (TLM) and finite-difference-time-domain (FD-TD) methods in two dimensions is discussed. A propagation analysis of a TLM shunt node complete with permittivity and loss stubs and a dispersion analysis of the two-dimensional FD-TD method in an arbitrary medium are performed and yield dispersion relations. The relations are identical when the FD-TD method is operated at the upper limit of its stability range. >

TL;DR: This letter presents a simple and fast algorithm to analyze wideband electromagnetic induction data for subsurface targets that provides a computationally faster way to reproduce the results of state-of-the-art methods.
Abstract: This letter presents a simple and fast algorithm to analyze wideband electromagnetic induction data for subsurface targets. A well-known four-parameter model is differentiated, resulting in a two-parameter model. A fast lookup table is used to find parameters as opposed to nonlinear optimization. The proposed approach provides a computationally faster way to reproduce the results of state-of-the-art methods. A detailed mathematical analysis of the model is given that describes the advantages and limitations of the proposed method.
