We observe\r\nstrong modulations in the dispersion curves of Smith-Purcell radiation (SPR) when they intersect the surface\r\nplasmons of silver gratings using a 200-kV transmission electron microscope. The decay of the plasmons away\r\nfrom the grating is directly probed by controlling the electron-beam position relative to the sample surface\r\nwith nanometer precision. Our measurements are in excellent agreement with numerical simulations, clearly\r\nrevealing the presence of characteristic Fano profiles resulting from the interference of the light continuum\r\nand the discrete plasmon states for each direction of emission. The intensity anomaly in the SPR emission\r\npattern can be well explained from the geometrical consideration of the intersections between the dispersion\r\nplanes of the SPR and surface plasmon polariton (SPP). A strong and directional SPR beam can be realized\r\nunder the condition that the SPR dispersion plane comes in contact with the band edge of the SPP dispersion\r\nplane.","lang":"eng"}],"ddc":["530"],"citation":{"ieee":"N.
