This paper presents a planar and compact microwave resonator sensor to characterize materials. The geometry of the resonator is based on the Sierpinski fractal curve and has four poles in the frequency range from 0.5 GHz to 5.5 GHz. Any of the four p

Fractal Graphene Patch Antennas and the THz Communications Revolution

Autor: Alberto Boretti, Jonathan Blackledge, Stefania Castelletto, Lorenzo Rosa

Publikováno v: Conference papers

Fractal antennas have and are continuing to receive attention in regard to the future of wireless communications. This is because of their wide- and multi-band capabilities, the opportunity of fractal geometries to drive multiple resonances, and, the

A Preliminary Study of a Graphene Fractal Sierpinski Antenna

Autor: Stefania Castelletto, Jonathan Blackledge, Alberto Boretti, Lorenzo Rosa

Publikováno v: Conference papers

We provide a preliminary study of a Graphene fractal antenna operating at THz frequencies with the opportunity to modulate the emission. There are many advantages of the fractal design, namely multiband/wideband ability, and, a smaller, lighter and s

Publikováno v: Optics Express

Cataloged from PDF version of article. We introduced fractal geometry to the conventional bowtie antennas. We experimentally and numerically showed that the resonance of the bowtie antennas goes to longer wavelengths, after each fractalization step,

Analytic expression for the mean time to absorption for a random walker on the Sierpinski fractal. III. the effect of non-nearest-neighbor jumps

Autor: V. Balakrishnan, John J. Kozak

Publikováno v: IndraStra Global.

We present exact, analytic results for the mean time to trapping of a random walker on the class of deterministic Sierpinski graphs embedded in d?2 Euclidean dimensions, when both nearest-neighbor (NN) and next-nearest-neighbor (NNN) jumps are includ
