Please exmlaine me these structures:

If I clear undestand these data come from FDTD(or RCWA calculation) which has been done for the Pillars with different radius. That why numbers of E(or H) is equal 361. Then we have the 9 points with coordinate in X and Y direction. Each point corresponding to the Electrical Filed and Magnetical Field in the First Frenel Zone . The number 1,2,3..., 361 is indexs which link the radius data of Pilars and the Electromagnetic Field in near region .

How can I calculate phase which describe by one number from -pi to pi using the 18 values of Fields?
