Research on the Eigentime and Related Problems of the Corresponding Fractal Network of Sierpiński Fractal Antenna

This paper studies the eigentime and related issues in the fractal network corresponding to the Sierpiński fractal antenna. The access time or hitting time H (i, j) is the expected number of steps before node j is visited, starting from node i . The eigentime of G is the expectation of H (i, j) for all i, j ∈G . Classical eigenvalue method let H (i, i) =0. However, when studying the random walk behavior. of electrons in fractal networks corresponding to fractal antennas, it is necessary to consider the time when electrons leave a certain node and first return to that node (self return time) . This paper adopts two research methods-the eigenvalue method based on spectral theory and the Markov chain method based on stochastic process theory-to obtain the modified intrinsic time, and demonstrates through an example that the difference between the classical intrinsic time and the modified intrinsic time is precisely due to the self return time. This paper shows the applications of fractal networks in modern communications. The research results are expected to provide a theoretical basis for the design and performance optimization of fractal antennas.
