  journal={arXiv: Computational Physics},
A lumped-parameter impedor-oriented and a 2-port-network-oriented circuit models for the Sierpinski gasket prefractal antenna are presented. With the former, the voltage and current patterns give a detailed understanding of the electromagnetic fields' self-similar distribution throughout the antenna geometry; on the other hand model complexity exponentially increases with the prefractal iteration order. The latter "black-box" model only controls port-oriented global parameters which are the… Expand
An Electrical Model to Sierpenski Gasket Patch Antenna
The proposed model has the same resonant frequency with the antenna and a few differences in band width and it’s very useful for parametric analysis of the Sierpenski gasket antenna. Expand
Analysis and Design of Printed Fractal Antennas by Using an Adequate Electrical Model
Two electrical models of carpet and gasket Sierpenski patch antenna are proposed, in which the antenna structure is replaced by its equivalent rectangular patch and the resonant RLC parameters are extracted. Expand

Rigorous uncertainty quantification without integral testing
It is shown that, for systems that have the structure of an acyclic graph, it is possible to obtain rigorous upper bounds on the probability of failure of the entire system from an uncertainty analysis of the individual components and their interfaces and without the need for integral testing.

On the behavior of the Sierpinski multiband fractal antenna
The multiband behavior of the fractal Sierpinski (1915) antenna is described. Due to its mainly triangular shape, the antenna is compared to the well-known single-band bow-tie antenna. BothExpand

A simple model that explains the behavior of the Sierpinski fractal antenna is presented. This model shows that the multiband behavior of the Sierpinski fractal antenna is a consequence of itsExpand
Spectral analysis of Serpinskij carpet-like prefractal waveguides and resonators
Exact results on some modal properties of waveguides and resonators is studied, whose geometry is derived from "Serpinskij carpet-like" prefractals (Serpinskij carpet and sponge; Menger sponge). TheExpand
