Convert linear component representation of field to circular component representation
Express a 45° linear polarized field in terms of right-circular and left-circular components.
fv = [2;2] cfv = pol2circpol(fv)
cfv = 1.4142 - 1.4142i 1.4142 + 1.4142i
Specify two input fields [1+1i;-1+1i] and [1;1] in the same matrix. The first field is a linear representation of a left-circularly polarized field and the second is a linearly polarized field.
fv=[1+1i 1;-1+1i 1] cfv = pol2circpol(fv)
cfv = 1.4142 + 1.4142i 0.7071 - 0.7071i 0.0000 + 0.0000i 0.7071 + 0.7071i
Field vector in its linear component representation specified as a 1-by-N complex row vector or a 2-by-N complex matrix. If fv is a matrix, each column in fv represents a field in the form of [Eh;Ev], where Eh and Ev are the field's horizontal and vertical polarization components. If fv is a vector, each entry in fv is assumed to contain the polarization ratio, Ev/Eh. For a row vector, the value Inf designates the case when the ratio is computed for a field with Eh = 0.
Example: 2 + pi/3*i
Data Types: double
Complex Number Support: Yes
Field vector in circular component representation returned as a 1-by-N complex-valued row vector or 2-by-Ncomplex-valued matrix. cfv has the same dimensions as fv. If fv is a matrix, each column of cfv contains the circular polarization components, [El;Er], of the field where El and Er are the left-circular and right-circular polarization components. If fv is a row vector, then cfv is also a row vector and each entry in cfv contains the circular polarization ratio, defined as Er/El.
