Based on the Wigner transform, a method for designing a self-accelerating beam is proposed. As an example, a beam traveling along an arbitrary path has been studied by modulating the phase of an optical field. Meanwhile, the effect of the amplitude m

Background: Historical reports on surgical renal denervation consistently describe renal plexus as a triangle or fan-like structure converging at the kidney gate. Following that anatomy, we developed a distal mode of radiofrequency renal denervation
