“…22 When a THz pulse is incident along the c-axis of the crystal, the magnetic field of the THz pulse can couple with the quasiferromagnetic mode at the frequency of 0.299 THz due to the magnetic dipole transition. 23 At the same time, the electric field of the THz wave can excite both ordinary and extraordinary polarization of the crystal, and birefringence occurs for the incident THz wave.…”

We present the magnetic dipole transition at 0.299 THz excited by magnetic component of terahertz electromagnetic pulse in an antiferromagnetic YFeO3 crystal. The impulsive magnetic field of the terahertz pulse tilts the macroscopic magnetization, causing deviation from the equilibrium position, which is manifested by a sharp absorption at the frequency of the quasiferromagnetic mode of the crystal. The rotating coherent macroscopic magnetization radiates elliptically polarized emission at the frequency of the quasiferromagnetic resonance due to the dichroic absorption in the crystal.

“…3, the investigation of birefringence in the THz spectral range is a wide field with numerous applications. In literature, in many cases birefringence was determined for samples with known orientation of the optical axis, such as for crystals [35,36,38], LCs [43][44][45][46][47][48][49][50][51][52] or form birefringent samples [59][60][61]. Theoretical considerations on how to choose appropriate Jones vectors for data analysis based on previous knowledge of the investigated sample and the detection geometry were presented in [95], underlined by experimental data for a birefringent quartz crystal.…”

In the last few years, various studies on terahertz (THz) birefringence have been presented, based on polarization-sensitive THz time-domain spectroscopy. The field of THz birefringence is a wide one covering several aspects, such as different materials exhibiting THz birefringence, polarization-sensitive THz technology, as well as numerous methods for extracting the birefringence properties of a sample from the THz data. Therefore, this paper aims at reviewing recent results on THz birefringence measurements presented in literature, addressing the above aspects and giving an overview of the topic. Moreover, it will focus on the investigation of birefringent fibrous samples, where specific results will be discussed in detail. Altogether, this paper should give a comprehensive view on the recent achievements in the measurements of THz birefringence.

“…The period along x-direction is fixed at 360 μm, while the period along y-direction is varied from 80 μm to 320 μm with step of 80 μm. The transmission spectra were measured by using a standard terahertz timedomain spectroscopy system [22,23] with effective spectral range of 0.1 to 1.6 THz generated from a low-temperature-grown GaAs emitter. For all transmission measurement, the THz wave with polarization is perpendicular to the long edge of the rectangular holes impinging on the sample at normal incidence (along y-direction as shown in Fig.…”

The Extraordinary Transmission Spectrum in Terahertz Regime: Combination of Shape Resonances and Rayleigh anomalies

We present the Terahertz wave extraordinary transmission through thin metal film with periodic arrays of subwavelength rectangular holes. By designing metallic hole arrays with different periods along x and y direction, the transmission spectrum with a non-Fano type is obtained. The roles of shape resonances and Rayleigh anomalies in extraordinary transmission are clarified. Our results demonstrate that the enhanced transmission can be attributed to the shape resonance, and the position of transmission minimum comes from the Rayleigh anomaly which is related to the period of the holes array. Shape resonance in hole arrays is different from the classical waveguide resonance, instead, the resonance behaves a surface plasmon polariton-like character but it is irrelevant to the period of the hole arrays. Our finding is applicable to exploit terahertz field localization which can be used to study terahertz nonlinear spectroscopy of materials.
