Boundedness of pseudo-differential operators via coupled fractional Fourier transform

Applicable Analysis
In this article, we obtained some fruitful results of the coupled fractional Fourier transform and its kernel. We defined pseudo-differential operators related to coupled fractional Fourier transform on Schwartz spaces and it is shown that their ...

Asymmetric multiple-image encryption based on coupled logistic maps in fractional Fourier transform domain

Optics and Lasers in Engineering, 2014
Abstract A multiple-image encryption scheme is proposed based on the asymmetric technique, in which the encryption keys are not identical to the decryption ones. First, each plain image is scrambled based on a sequence of chaotic pairs generated with a system of two symmetrically coupled identical logistic maps.

On the extension of the coupled fractional Fourier transform and its properties

Integral Transforms and Special Functions, 2021
The coupled fractional Fourier transform is a two-dimensional fractional Fourier transform that depends on two angles that are coupled in such a way that the transform parameters are and It generalizes the two-dimensional Fourier transform and it serves ...

On the Extension and Sampling Theorem for the Coupled Fractional Fourier Transform

2023 International Conference on Sampling Theory and Applications (SampTA), 2023
The fractional Fourier transform, denoted by Fθ, which is a generalization of the Fourier transform, depends on a parameter 0 ≤ θ ≤ π/2, so that when θ = 0, F0 is the identity transformation and when θ = π/2, Fπ/2 is the standard Fourier transform.
