Abstract In this paper, we propose a terahertz (THz) guided-mode resonance (GMR) notch filter made of a monolithic polyethylene terephthalate (PET) film, which has a monolayer grating structure. The proposed configuration shows both polarization-depe

A quadrupole mass filter consists of four equidistant parallel rods. Each opposing rod pair is connected electrically, and direct current (DC) and radio frequency alternating current (AC) potentials are applied between one pair of rods and the other.

The deflection of charged particles is an intuitive way to visualize an electromagnetic oscillation of coherent light. Here, we present a real-time ultrafast oscilloscope for time-frozen visualization of a terahertz (THz) optical wave by probing ligh
