Unfortunate dilemmas in theory of electrical engineering The paper represents (to some extent in the form of a feuilleton) an essay on some essential postulates of the theory of electrical engineering. Although nowadays their modification is already no longer real and desirable, it is possible to notice that their opposite ve... |

„Curvilinear squares“ in the teaching of electric fields The method of “the curvilinear squares” was first described by Dr. Lehmann in year 1909 [1]. It allows a graphical solution of partial differential equations of the elliptic type. It was used for solving technical problems in the first half of last century. More ef... |

Artificial dielectric substrate for microwave applications This paper presents a new version of an artificial dielectric substrate. The substrate is fabricated as a 2D array of metallic posts separated from the top conductor by a thin dielectric slab. This structure can show a very high effective permittivity. This permittivity ... |

Operation parameters and characteristic of aactuators with dilatation element In specific applications one needs actuators characterized by very high forces at small shifts. As actuators of classical constructions mostly cannot satisfy these requirements, the authors designed another arrangement with an inductively heated dilatation element. But huge mechanical strains&#... |
