Abstract:
Frustrated total internal reflection (FTIR) is analyzed from a novel perspective. Unlike similar works, the angle of incidence is used here as the experimental variable instead of the film thickness through which light tunnels. This method makes it possible to visualize not only the phenomenon of FTIR but also the resonance processes that occur for angles of incidence below the critical angle. An affordable straightforward experiment appropriate for undergraduates is presented. The experiment involves measuring the reflection and transmission of light through a pair of prisms separated by an a

Abstract We use a ‘Cantenna’ (portmanteau of ‘Can’ and ‘Antenna’), which is a unidirectional homemade waveguide, coupled to a standard readily available, 2.4 GHz Wi-Fi router as a source of microwaves to demonstrate Frustrated Total Internal reflection (FTIR) using paraffin-wax prisms. This largely inexpensive experiment provides an opportunity to demonstrate a process closely analogous to quantum tunnelling in an undergraduate physics lab. FTIR is often demonstrated with glass prisms and lasers, which may not allow for an intuitive understanding of evanescent waves and tunnelling. Wi-Fi signa

The frustrated total internal reflection (FTIR) optical fingerprint scanning method is widely used due to its cost-effectiveness. However, fingerprint image quality is highly dependent on fingertip surface conditions, with moisture generally considered a degrading factor. Interestingly, a prior study reported that excessive moisture may improve image quality, though their findings were based on qualitative observations, necessitating further quantitative analysis.

Abstract:
Quantum tunneling is a phenomenon in which an atom or a subatomic particle appears on the other side of a potential barrier that should be impenetrable to the particle, given the difference between the kinetic energy of the particle and the potential energy of the barrier, the former being significantly lesser. However, if the barrier shrinks enough the particle will be able to tunnel right through it. This is among the most well-known quantum physics phenomena. Historically, physicists struggled to grasp the wavelike and particle-like duality of light and subatomic particles. The aforemention
