Golden Vogel spirals, as deterministic aperiodic structures, support isotropic photonic band
gaps and have interesting applications. Localized modes, such as band-edge states, are …

Practical formulas are derived for calculating the far-field radiation pattern and coupling
coefficient of a rectangular dielectric resonator (cuboid) with free space as well as mutual …

The coupled-mode theory is an established and important tool in the electromagnetic theory
which describes the exchange of energy between modes of a given system. In the …

The coefficients of mutual coupling of rectangular dielectric resonators in open space are
calculated under the condition of their rotation relative to one of the axes of a given …

Um estudo de conjuntos de antenas com geometria da espiral de Vogel é realizado. Tal
estudo mostra, através da análise das características das espirais e do padrão de radiação …

The coupling coefficients of cylindrical dielectric resonators with a regular rectangular
waveguide under the condition their axes rotation are calculated. The dependences of the …

Background. A further increase in the speed of information transfer is determined by more
stringent requirements for the elements of communication devices. One of the most …
