The Meissner equation is a linear ordinary differential equation that is a special case of Hill's equation with the periodic function given as a square wave.
[1] [2] There are many ways to write the Meissner equation.
It is also useful for understand resonance problems in evolutionary biology.
Because the time-dependence is piecewise linear, many calculations can be performed exactly, unlike for the Mathieu equation.
, the Floquet exponents are roots of the quadratic equation The determinant of the Floquet matrix is 1, implying that origin is a center if
