Fig. 2: The UMA for simultaneous manipulations of the radiated EM wave properties.

From: A universal metasurface antenna to manipulate all fundamental characteristics of electromagnetic waves

Fig. 2

a–c Measured far-filed radiation patterns of the UMA at the fundamental frequency with the |x〉 polarization, whose main beam scans to −40o (a), 0o (b) and 40o (c), respectively. d–f Same as (a–c), except that the polarization is changed to |u〉. g–i Same as (d–f), except that the frequency of the extracted PW is changed to the m = +1 harmonic. Three curves in each panel demonstrate the amplitude controls of the radiated PWs. The input frequency and modulation frequency are f0 = 23.5 GHz and fM = 1.2 MHz, respectively.
