In classical electromagnetism, reciprocity refers to a variety of related theorems involving the interchange of time-harmonic electric current densities (sources) and the resulting electromagnetic fields in Maxwell's equations for time-invariant linear media under certain constraints. Reciprocity is closely related to the concept of symmetric operators from linear algebra, applied to electromagnetism. WebbComplex Roots. Complex roots are the imaginary root of quadratic or polynomial functions. These complex roots are a form of complex numbers and are represented as α = a + ib, and β = c + id. The quadratic equation having a discriminant value lesser than zero (D<0) have imaginary roots, which are represented as complex numbers.
