Erratum: Spherical representation of omnipotent Smith chart

An Interactive Smith Chart

Smith is an instructional, interactive, menu driven program that offers the use of Smith Chart on a personal computer. Using the Smith Chart is greatly simplified by providing the user with a “tracking mode” in which the cursor is tracked, showing the normalized resistance and reactance as well as distances from source and load. Also, construction lines such as radius, diameter and circles can ...

A Novel Neural Smith Chart for Use in Microwave Circuitry

In this article, briefly the Smith chart is mapped with an artificial neural network (ANN) covering its whole details to be exploited CAD of the microwave circuitry. Thus, relative to the similar works in the existing literature, this article provides the continuous Smith chart domain to facilitate the ‘‘Smith chart’’ methodology in solving the highly nonlinear transformation equations between ...

Adaptive multi-chart and multiresolution mesh representation

In this paper, we present an adaptive multi-chart and multiresolution mesh representation suitable for both the CPU and the GPU. We build our representation by simplifying a dense-polygon mesh to a base mesh and storing the original geometry in an atlas structure. For both simplification and resolution control, we extend a hierarchical method based on stellar operators to the GPU context. Durin...

Multiscale Representation and Analysis of Spherical Data by Spherical Wavelets

Classic wavelet methods were developed in the Euclidean spaces for multiscale representation and analysis of regularly sampled signals (time series) and images. This paper introduces a method of representing scattered spherical data by multiscale spherical wavelets. The method extends the recent pioneering work of Narcowich and Ward [Appl. Comput. Harmon. Anal., 3 (1996), pp. 324–336] by employ...
