A Study of a Wide-Angle Scanning Phased Array Based on a High-Impedance Surface Ground Plane

Figure 13

Comparison of field distributions and energy flow directions between the LW eigenfield and the radiation field of the array at a radiation angle of 60°, where the color distribution and the arrow direction represent the magnitude of the magnetic field and the direction of the Poynting vector, respectively. (a) LW mode eigenfield and the direction of the Poynting vector; (b) total field and the direction of the Poynting vector of our array.
