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...

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...

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...

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...
