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, which is considered a tool to miniaturize the main bowtie structure. We also showed that the fractal geometry provides multiple hot spots on the surface, and it can be used as an efficient SERS substrate. © 2014 Optical Society of America.

Comparison of Back and Top Gating Schemes with Tunable Graphene Fractal Metasurfaces
(American Chemical Society, 2016)In this work, fractal metasurfaces that consist of periodic gold squares on graphene are used to increase light-graphene interaction. We show by simulations and experiments that higher level fractal structures result in ... -
Bidding structure, market efficiency and persistence in a multi-time tariff setting
(Elsevier, 2016)The purpose of this study is to examine the fractal dynamics of day ahead electricity prices by using parametric and semi parametric approaches for each time zone in a multi-time tariff setting in the framework of bidding ... -
Generating connected textured fractal patterns using Markov random fields
(1991)An algorithm that yields textured and connected binary fractals is presented. The texture is imposed by modeling the fractal as a Markov random field (MRF) at every resolution level. The model size and the parameters specify ...
