چکیده

A formula for the interior ε-neighbourhood of the classical von Koch snowflake curve is computed in detail. This function of ε is shown to match quite closely with earlier predictions from [La-vF1] of what it should be, but is also much more precise. The resulting ‘tube formula’ is expressed in terms of the Fourier coefficients of a suitable nonlinear and periodic analogue of the standard Cantor staircase function and reflects the self-similarity of the Koch curve. As a consequence, the possible complex dimensions of the Koch snowflake are computed explicitly.

New Escape Time Koch Curve in Complex Plane

Von Koch curves allow numerous variations and have inspired many researchers and fractal artists to produce amazing pieces of art. In this paper we present a new algorithm for plotting the Koch curve using complex variables. Further we have applied various coloring algorithms to generate complex Koch fractals.

Design of koch fractal bow tie antenna for wireless applications

The crowding of wireless band has necessitated the development of multiband and wideband wireless antennas. Because of the self similar characteristics, fractal concepts have emerged as a design methodology for compact multiband antennas. A Koch-like fractal curve is proposed to transform ultra-wideband (UWB) bow-tie into so called Koch-like sided fractal bow-tie dipole. A small isosceles trian...

Study and Analysis of Triangular Koch Curve and Sierpinski Fractal Geometries for Antenna Designing

As today’s communication devices are becoming smaller in size, they need antennas also of small size which are capable of providing higher performance. Modern telecommunication systems need antennas with wider bandwidth, multiband support, low cost and conventionally smaller design dimensions for commercial as well as military applications. This ever increasing demand of small, multiband antenn...

Vibration of the Koch drum

The Koch snowflake is a well known self-similar set whose boundary is a fractal curve. Suppose a vibrating membrane with fixed boundary, i.e. a drum, is shaped like a Koch snowflake. The fundamental modes of vibration of this drum can be modelled by the eigenfunctions of the Laplacian on the snowflake. These, in turn, can be approximated by a discrete problem leading to a matrix eigenvalue prob...
