Applications and Applied Mathematics: An International Journal (AAM)
Classical waveguide theory has been developed bearing on Bernoulli’s product method which results in separation of space and time variables in Maxwell’s equations. The time-harmonic waveguide modes have been stated mathematically for transmitting signals along the waveguides. As a starting point, present studies on transverse-electric (TE) and transverse-magnetic (TM) waveguide modes with previous results are taken and exhibited in an advanced form. They have been obtained within the framework of an evolutionary approach to solve Maxwell’s equations with time derivative. As a result every modal field is obtained in the form of a product of vector functions of transverse coordinates …

Damming Brazil, Thyra Brody
e-Research: A Journal of Undergraduate Work
Hydroelectric power is often considered a safe and clean alternative to the combustion of fossil fuels. Although the consequences to the air and atmosphere are lower, damming large rivers in the jungles of Brazil have a significant impact on indigenous populations and environmental ecosystems. This article examines such fallout and calls out for equity, and social and environmental justice. As the fuel of the last century burns out the hectic scramble for a tenable alternative is becoming an increasingly serious question mark. We would do well for ourselves, and future generations, to try and solve the environmental issues associated with …
Deriving The Snel-Descartes Law For A Single Photon, Randy Wayne
Deriving The Snel-Descartes Law For A Single Photon, Randy Wayne
Turkish Journal of Physics
The laws of reflection and refraction are typically derived using a dispersion relation that assumes that the angular frequency stays the same across a vacuum--dielectric interface and that the angular wave number increases. At the single photon level, this means that the total energy of the photon is conserved but the linear momentum is not. Here I derive the laws of reflection and refraction for a single photon using a dispersion relation that is consistent with the conservation of both total energy and linear momentum. To ensure that both conservation laws are upheld, the optical path length must be considered …
