Show the condition such that
the total field of two linearly polarized waves with crossing angle θ
becomes a circularly polarized wave,
where A and B are complex numbers.
Example 1 (Circularly polarized wave)
An animation of the total field of A=ra exp(j θa) and B=rb exp(j θb) in the case that θ=30°,ra=rb=1,θa=0°,θb=θ+180°
Example 2 (Circularly polarized wave)
An animation of the total field of A=ra exp(j θa) and B=rb exp(j θb) in the case that θ=90°,ra=rb=1,θa=0°,θb=θ+180°
Example 3 (Elliptically polarized wave)
An animation of the total field of A=ra exp(j θa) and B=rb exp(j θb) in the case that θ=90,ra=1,rb=1/2,θa=0°,θb=θ+180°
