Quantum graphs and microwave networks as narrow band filters for quantum and microwave devices
Afshin Akhshani, Małgorzata Białous, Leszek Sirko
We investigate properties of the transmission amplitude of quantum graphs and microwave networks composed of regular polygons such as triangles and squares. We show that for the gr…
Distributions of the Wigner reaction matrix for microwave networks with symplectic symmetry in the presence of absorption
Michal Lawniczak, Afshin Akhshani, Omer Farooq +4
We report on experimental studies of the distribution of the reflection coefficients, and the imaginary and real parts of Wigner's reaction (K) matrix employing open microwave netw…
Notes on Dynamics of an External Cavity Semiconductor Lasers
S. Behnia, Kh. Mabhouti, A. Jafari +1
Dynamics of external cavity semiconductor lasers is known to be a complex and uncontrollable phenomenon. Due to the lack of experimental studies on the nature of the external cavit…
Applications of tripled chaotic maps in cryptography
Sohrab Behnia, Afshin Akhshani, Amir Akhavan +1
Security of information has become a major issue during the last decades. New algorithms based on chaotic maps were suggested for protection of different types of multimedia data,…
Chaotic Cryptographic Scheme Based on Composition Maps
S. Behnia, A. Akhshani, A. Akhavan +1
In recent years, a growing number of cryptosystems based on chaos have been proposed. But most of them encountered many problems such as small key space and weak security. In the p…
