Modal Phenomena in the Natural Electromagnetic Spectrum Below 5 kHz
This paper presents new measurements of the magnetic field component of naturally–produced electromagnetic radiation in the ELF/VLF range. The measurements are compared to calculations based on modal propagation theory. The nocturnal spectrum below 5 kHz often contains a sharp increase in spectral level at the cutoff frequency of the first mode (∼1700 Hz), and a distinct variation of the spectr...
متن کاملElectromagnetic Theory -
Magnetomotive force (mmf) Magnetomotive force is the flux producing ability of an electric current in a magnetic circuit. [It is something similar to electromotive force in an electric circuit]. [Unit of magnetomotive force is ampere (A)] Note: Although some books use the term ampere-turns, it is strictly not correct as turns is not a dimension] mmf I = Σ I Consider a coil having N turns as sho...
متن کاملElectromagnetic Theory on a Lattice
In this paper, a self-contained electromagnetic theory is derived on a regular lattice. The discretized form of integral and diierential calculus, which is called`discrete calculus' here, is used to describe this theory. It is shown that discrete forms of Gauss' theorem, Stokes' theorem, Green's theorem, and Huygens' principle can be derived. Moreover, many electromagnetic theorems can also be ...
متن کاملNovel Resonance - Assisted Electromagnetic - Transport Phenomena
We first demonstrate theoretically and experimentally that electromagnetic resonators with high quality factors (Q) can be used to transfer power efficiently over distances substantially larger than the characteristic dimensions of the resonators by operating in a so-called "strongly coupled" regime. We next generalize the notion of strongly coupled resonances to a system comprising one power s...
