Simulated field distributions of QCM, PAM and RAM. Schematic diagram of 8-fold QCM (a), PAM (e) and RAM (i) with slits patterned on metallic films. Inset of (a): enlarged single slit with the width of a = 60 μm and length of b = 150 μm. (b–d) Simulated SP distributions of the 8-fold QCM at frequencies of 0.58 (b), 0.78 (c), and 1 THz (d). (f–h) Simulated SP distributions of PAM at 0.58, 0.78, and 1 THz, respectively. (j–l) Corresponding SP distributions of RAM at three frequencies, respectively.
