Abstract
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.

Bidding structure, market efficiency and persistence in a multi-time tariff setting
Avci-Surucu, E.; Aydogan, A. K.; Akgul, D. (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
Onural, L. (Institute of Electrical and Electronics Engineers, 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 ... -
Spectra of self-similar Laplacians on the Sierpinski gasket with twists
Blasiak, A.; Strichartz, R. S.; Ugurcan, B. E. (World Scientific Publishing Co. Pte. Ltd., 2008)We study the spectra of a two-parameter family of self-similar Laplacians on the Sierpinski gasket (SG) with twists. By this we mean that instead of the usual IFS that yields SG as its invariant set, we compose each mapping ...
