system analysis, a phase plane is a visual display of certain characteristics of certain kinds of differential equations; a coordinate plane with axes being...

space; a one-dimensional system is called a phase line, while a two-dimensional system is called a phase plane. For every possible state of the system or...

In mathematics, a phase portrait is a geometric representation of the orbits of a dynamical system in the phase plane. Each set of initial conditions...

output of E-Plane Tee is 180° out of phase where the output of H-plane Tee is in phase. For a linearly-polarized antenna, this is the plane containing...

A lunar phase or Moon phase is the apparent shape of the Moon's directly sunlit portion as viewed from the Earth (because the Moon is tidally locked with...

of phasors, which may have arbitrary magnitude (i.e. not necessarily on the unit circle in the complex plane). Multiplying the equation of a plane wave...

side (s-plane imaginary line) or outside (z-plane unit circle) of the complex plane lead to unstable systems, only the class of minimum-phase systems...

antenna is a phased array in which the individual antennas, instead of being arranged in a flat plane, are mounted on a curved surface. The phase shifters...

In physics and mathematics, the phase (symbol φ or ϕ) of a wave or other periodic function F {\displaystyle F} of some real variable t {\displaystyle...

In classical and quantum mechanics, geometric phase is a phase difference acquired over the course of a cycle, when a system is subjected to cyclic adiabatic...
