Multifaceted terahertz applications of parallel-plate waveguide: TE1 mode
Presented is a review of recent work by the authors in which the lowestorder transverse-electric (TE1) mode of a parallel-plate waveguide (PPWG) is used for terahertz (THz) applications. This work adds a new dimension to the multitude of diverse THz applications made possible by PPWGs. Using the TE1 mode, demonstration is presented of an ultra-low loss THz waveguide, a highly sensitive microflu...
متن کاملTerahertz mirage: Deflecting terahertz beams in an inhomogeneous artificial dielectric based on a parallel-plate waveguide
The field of metamaterials and the formalism of transformation optics have provided a prescription for constructing artificial dielectrics with unique properties such as light trapping and cloaking. Here, we describe a different approach to creating an inhomogeneous artificial medium, based on waveguide techniques, which does not rely on engineered subwavelengthscale components. We demonstrate ...
متن کاملFocused terahertz waves generated by a phase velocity gradient in a parallel-plate waveguide.
We demonstrate the focusing of a free-space THz beam emerging from a leaky parallel-plate waveguide (PPWG). Focusing is accomplished by grading the launch angle of the leaky wave using a PPWG with gradient plate separation. Inside the PPWG, the phase velocity of the guided TE1 mode exceeds the vacuum light speed, allowing the wave to leak into free space from a slit cut along the top plate. Sin...
متن کاملTerahertz field enhancement to the MV/cm regime in a tapered parallel plate waveguide.
We investigate field enhancement properties of a tapered parallel plate waveguide for ultrashort terahertz (THz) pulses. We use two independent methods, air biased coherent detection inside the waveguide and free-space electro-optic sampling, respectively, which enables a calibrated, quantitative measurement of the field strength at the output of the waveguide. Field enhancement factors greater...
متن کاملPropagation of Single-Mode and Multi-Mode Terahertz Radiation Through a Parallel-Plate Waveguide
We investigated the propagation of singleand multi-mode terahertz (THz) radiation through a parallel-plate waveguide for various gap sizes of the plates and polarizations of the incoming THz eld. Single TEM (TM0) and TE1 modes within the 4-THz frequency range propagated through a waveguide with a plate separation of 103 m. Multi TE and TM modes were observed for a 360m separation. High-order mo...
