From Fundamentals to Applications
Among the
branches of classical physics, electromagnetism is the domain which
experiences the most spectacular development, both in its fundamental
and practical aspects. The quantum corrections which generate non-linear
terms of the standard Maxwell equations, their specific form in curved
spaces, whose predictions can be confronted with the cosmic polarization
rotation, or the topological model of electromagnetism, constructed
with electromagnetic knots, are significant examples of recent
theoretical developments. The similarities of the Sturm-Liouville
problems in electromagnetism and quantum mechanics make possible deep
analogies between the wave propagation in waveguides, ballistic electron
movement in mesoscopic conductors and light propagation on optical
fibers, facilitating a better understanding of these topics and
fostering the transfer of techniques and results from one domain to
another. Industrial applications, like magnetic refrigeration at room
temperature or use of metamaterials for antenna couplers and covers, are
of utmost practical interest. So, this book offers an interesting and
useful reading for a broad category of specialists.
