41Step potential — The Schrödinger equation for a one dimensional step potential is a model system in quantum mechanics and scattering theory. The problem consists of solving the time independent Schrödinger equation for a particle with a step like potential in one …
42Step response — The step response of a system in a given initial state consists of the time evolution of its outputs when its control inputs are Heaviside step functions. In electronic engineering and control theory, step response is the time behaviour of the… …
43Ionosphere — The ionosphere is a part of the upper atmosphere, comprising portions of the mesosphere, thermosphere and exosphere, distinguished because it is ionized by solar radiation. It plays an important part in atmospheric electricity and forms the inner …
