Abstract

We report on the terahertz transmission properties through a single slit in a thin metallic film. The properties are studied by comparing the transmissions of TE- and TM-polarized electromagnetic waves over a broad spectral range from the geometrical regime to the subwavelength limit. In the geometrical regime, the remarkable terahertz transmission due to guided modes is observed even without the contribution of surface waves. Whereas in the subwavelength limit, the surface charge oscillations associated with the TM-polarized guided mode give rise to strong transmission enhancement. The nature of the mechanisms for the terahertz transmission is elucidated using theoretical simulations of the near-field distributions and electromagnetic energy flow.

(a) Schematics of our THz time-domain spectroscopy system and sample geometry. (b) Time traces of the incident THz wave (black line) and the TE- (blue line) and TM- (red line) polarized transmission amplitudes for the sample with the slit width of 400 μm, at normal incidence. (c) THz transmission spectra obtained by Fourier transforming the time traces of (b).

Fig. 2

(a) Measured TE-polarized transmission amplitude spectra normalized by the corresponding TM-polarized transmission, for samples with different slit widths from 100 to 800 μm. The curves are vertically offset for clarity of presentation. (b) Measured spectral peak positions (dots) of the first three guided modes plotted versus the half wavelength cutoff frequency. The spectral positions of the three guided modes are extracted from arrows in 2(a). The lines represent the theoretically predicted values. (c) Theoretically predicted, spatial electric field distributions of the first (black curve), second (red curve), third (blue curve) guided modes inside the slits.

Near electric field distributions (left) and time-averaged Poynting vectors (right), simulated at the wavelengths of 800 μm [(a) and (b)] and 160 μm [(c) and (d)], for a 400 μm width single slit under TE-polarized incident THz wave.

(a) Measured TM-polarized transmission amplitude spectra normalized by the corresponding TE-polarized transmission, for samples with different slit widths from 100 to 800 μm. (b) The ratio between the transmission amplitudes of TM- and TE-polarized incident waves, compared at four different frequencies of 0.15, 0.2 0.25 and 0.3 THz.

Fig. 5

Area-normalized enhancement factors of the TM-polarized transmitted amplitudes through four single slits of 200, 400, 600 and 800 μm. The transmitted amplitudes are divided by the reference signal (measured without a slit) and also by the ratio between the electromagnetic radiation impinging on the area of the slit and total incident radiation. This ratio is estimated using Gaussian beam optics to predict the properties of the focused input illumination.
