Polarization, the path traced by light's electric field vector, appears in all areas of optics. In
recent decades, various technologies have enabled the precise control of light's polarization …

The electromagnetic wave in the terahertz region shows many promising characteristics,
such as non-ionization,“fingerprint” spectrum, sensitivity to weak resonance, strong …

Birefringent materials—which are highly needed in high power laser systems—may be
limited in usage due to the laser‐induced damage threshold of traditional birefringent …

We present a low-cost terahertz wave plate based on form birefringence fabricated using
ordinary paper. Measurements of the transfer function of the wave plate between polarizers …

We review thin micro-optics components with nanostructured microreliefs intended to control
the polarization and phase of laser light. These components include transmission and …

We present simulation and experimental results for easily fabricated spiral plasmonic
antenna analogues providing circular polarization selectivity. One circular polarization state …

We have developed low-loss polymer artificial dielectric quarter wave plates (QWP)
operating at 2.6, 3.2 and 3.8 THz. The QWPs are imprinted on high density polyethylene …

Here, we present a 3D printed prism for THz waves made out of an artificial dielectric
material in which the dispersion can be tuned by external compression. The artificial …

A wave plate consisting of dielectric subwavelength gratings (SWGs) with a certain thickness
is typically used for polarization control. Since the phase retardation strongly depends on the …

We have developed anisotropically etched low-loss artificial dielectric birefringent quarter-
wave plates (QWPs) for use at 1.5 and 2.8 THz. The grating period for both QWPs is 20¿ m …
