Abstract :
Construction of energy-like expressions for various classes of anisotropic media and the use of the weighted residual technique for those cases that don´t obey Hermitian properties is undertaken. From the energy-like expressions are derived energy-like functionals, which are shown to have volumetric and surface parts. Volumetric parts contain electromagnetic governing equations of the media, and surface parts provide constraints on field components on interfacial boundaries. Media examined here include gyroelectric, gyromagnetic, combined gyroelectric and gyromagnetic, and complex media displaying gyroelectric, gyromagnetic, and optical activities
