Rudolf P. Huebenerms. The AMA method is based on taking the asymptotic limit of Classical Modal Analysis (CMA) as the number of modes in the structural system or acoustical system becomes large in a certain frequency bandwidth. While CMA requires both the computation of individual modes and a modal summation, AMA eva

The Discovery: Kamerlingh Onnes in Leiden,he world leader in this field. Kamerlingh Onnes was interested in the thermodynamic properties of gases and liquids at low temperatures. He was inspired by the research work of Johannes Diderik van der Waals at the University of Amsterdam.

Walther Meissner and the Physikalisch-Technische Reichsanstalt in Berlin,er was commissioned by Emil Warburg, the president of the Reichsanstalt, to build a hydrogen liquefaction plant. Before studying physics, Meissner had already graduated as a mechanical engineer, so he was well prepared for this task.

London Theory, Magnetic Penetration Depth, Intermediate State,In particular, their theory provides a value for the so-called magnetic penetration depth, within which the electric shielding currents flow along the surface of the superconductor and the magnetic field still exists in the superconductor. In the following, we refer to the magnetic penetration depth

Type II Superconductors, Abrikosov Vortex Lattice, Mixed State,n the field of superconductivity needed to be expanded. Shubnikov had built a low-temperature laboratory there early on, in which experiments could also be carried out with liquid helium. (However, Shubnikov’s many foreign contacts became his undoing during the Stalin terror of the time.
