ellipse

polarization ellipse parameters

Calling Sequence

[a,b,th] = ellipse(A,B,phi)

Parameters

A

magnitude of E-field x-component

B

magnitude of E-field y-component

phi

relative phase angle (in degrees) between x- and y-components (phi = phi_a - phi_b)

a

x-semiaxis

b

y-semiaxis

th

tilt angle (in degrees) of polarization ellipse measured from x-axis

Description

ellipse(A,B,phi) calculates polarization ellipse parameters

Examples

A   = [3, 3, 4, 3, 4, 3, 4, 3];
B   = [0, 4, 3, 3, 3, 4, 3, 4];
phi = [-90, 0, 180, 60, 45, -45, 135, -135];
[a,b,th] = ellipse(A,B,phi)
