Photonic tunneling permits superluminal signal transmission. The principle of causality is not violated but the time duration between cause and effect can be shortened compared with an interaction exchange with velocity of light. This outstanding property can be applied to speed-up photonic signal modulation and transmission as well as to improve micro-electronic devices. Superluminal photonic signal transmission have been presented at microwave and infrared frequencies already. Presumably…

Limitations on the principle of stationary phase when it is applied to tunneling analysis
Using a recently developed procedure - multiple wave packet decomposition - here we study the phase time formulation for tunneling or reflecting particles colliding with a potential barrier. To
Small corrections to the tunneling phase-time formulation
After reexamining the above-barrier diffusion problem where we notice that the wave packet collision implies the existence of multiple reflected and transmitted wave packets, we analyze the way of
RECOVERING THE STATIONARY PHASE CONDITION FOR ACCURATELY OBTAINING SCATTERING AND TUNNELING TIMES
The stationary phase method is often employed for computing tunneling phase times of analytically-continuous gaussian or infinite-bandwidth step pulses which collide with a potential barrier. The
ABOVE BARRIER POTENTIAL DIFFUSION
The stationary phase method is applied to diusion by a potential barrier for an incoming wave packet with energies greater than the height of the barrier. It is observed that a direct application
The Cosmological Significance of Superluminality
I remember well that day in 1997 when my teenage son was asking me: “Why is the speed of light so slow?” In fact, 299792458 m/s is a very finite velocity, and it is not too high regarding even the
Above potential barrier diffusion
The stationary phase method is applied to diffusion by a potential barrier for an incoming wave packet with energies greater then the barrier height. It is observed that a direct application leads to

Measurement of superluminal optical tunneling times in double-barrier photonic band gaps.
TLDR
Tunneling of optical pulses at 1.5 microm wavelength through double-barrier periodic fiber Bragg gratings is experimentally investigated and provides experimental evidence of the analogous phenomenon in quantum mechanics of nonresonant superluminal tunneling of particles across two successive potential barriers.

This revised picture resolves two disturbing mysteries: why many heart attacks strike without warning and why preventative therapies sometimes fail and highlights the need for better prevention, detection and treatment.
