Self-Similarity of Plasmon Edge Modes on Koch Fractal Antennas

Olivier Martin, Jérémy Butet, Gabriel David Bernasconi

We investigate the plasmonic behavior of Koch snowflake fractal geometries and their possible application as broadband optical antennas. Lithographically defined planar silver Koch fractal antennas were fabricated and characterized with high spatial and sp ...

On the accurate computation of the true contact-area in mechanical contact of random rough surfaces

Jean-François Molinari, Guillaume Anciaux, Vladislav Yastrebov

We introduce a corrective function to compensate errors in contact area computations coming from mesh discretization. The correction is based on geometrical arguments, and apart from the contact area itself requires only one additional quantity to be compu ...

Exploration of the Complex Similarity of Urban System Components

Matthieu Marie Cochon de Lapparent

Similar to countless natural phenomena, cities have inherent orders that can be properly captured and expressed through a complex analysis of their components. Using Geographic Information Systems (GIS), this work offers a ring-buffer fractal approach to a ...

Disorder-Driven Spin-Orbital Liquid Behavior in the Ba3XSb2O9 Materials

Frédéric Mila, Andrew James Smerald

Recent experiments on the Ba3XSb2O9 family have revealed materials that potentially realize spin-and spin-orbital liquid physics. However, the lattice structure of these materials is complicated due to the presence of charged X2+-Sb5+ dumbbells, with two p ...

Objective: Motor changes in major depression (MD) may represent potential markers of treatment response. Physiological rhythms (heart rate/gait cycle/hand movements) have been recently shown to be neither random nor regular but to display a fractal tempora ...

Apollonian packings as physical fractals

Francesco Varrato, Giuseppe Foffi

The Apollonian packings (APs) of spheres are fractals that result from a space-filling procedure. We discuss the finite size effects for finite intervals s is an element of [s(min), s(max)] between the largest and the smallest sizes of the filling spheres. ...

Fractal geometry and its applications in timber construction

Yves Weinand, Ivo Stotz, Gilles Gouaty, Eric Tosan

We have developed a geometric design method based on generalizations of IFS. We have shown that it is possible to extend the properties of fractal shapes to forms used in classical modeling (e.g Bézier or Splines). We have developed and studied a new forma ...

Methods and device to quantify human physical activity pattern

Kamiar Aminian, Anisoara Ionescu

The method for analyzing physical activity of a subject comprises: -) measuring at least one of body movement or posture of the subject using at least one sensor; -) defining a plurality of physical activity time series based on at least one of the measure ...

Innovation Modelling and Wavelet Analysis of Fractal Processes in Bio-Imaging

Michaël Unser, Dimitri Nestor Alice Van De Ville, Pouya Dehghani Tafti

Growth and form in biology are often associated with some level of fractality. Fractal characteristics have also been noted in a number of imaging modalities. These observations make fractal modelling relevant in the context of bio-imaging. In this paper, ...
