The Bessel beam, with a significant depth of field and self-healing characteristics, has been applied in widespread applications, including quantum entanglement, underwater 3D imaging, optical ...

(A) Optical image of the rGO electrode. (B and C) The SEM and EDS observations of the rGO electrode. (D) An optical axis view of the corresponding light intensity distribution of the Bessel beam.

The Bessel functions, denoted as J n (x), are used in engineering, acoustics, aeronautics, thermodynamics, theory of elasticity and others. For instance, in the electrical engineering field, they are ...

Bessel beam microscopy, and the techniques that preceded it, are generally used to image live cells in 3D. Bessel beams have a greater capability than other super-resolution imaging techniques for ...

The JROOT function returns an n ×2 matrix with the calculated roots in the first column and the derivatives in the second column. The inputs to the JROOT function are as follows: is a scalar denoting ...

This chapter is an introduction to some very interesting functions. These are special functions that find wide applications in science and engineering. They are solutions of differential equations ...
