Bøker av Beate (Humboldt University Meffert

Part of a series, this volume presents the research of professors' Harmuth and Meffert. It presents studies which raise fundamental questions concerning some of the basic areas of physics: electromagnetic theory and quantum mechanics. It is useful for those researchers and academics working in applied mathematicians or theoretical physics.

Features articles on the physics of electron devices (especially semiconductor devices), particle optics at high and low energies, microlithography, image science and digital image processing, electromagnetic wave propagation, electron microscopy, and the computing methods used in these domains.

Extend the calculus of finite differences to Dirac's equation. The authors obtain solutions for particles with negative mass that are completely equivalent to the solutions with positive mass. They also obtain solutions for nuclear distances of the order of 10-13m and less rather than for the usual atomic distances.
