Schematic of chiral terahertz generation and control: A femtosecond laser interacts with a patterned spintronic emitter, producing elliptically or circularly polarized terahertz waves. Rotating the ...
Light can carry angular momentum in two distinct ways. One comes from polarization, which describes how the electric field ...
A Chinese research team has developed a novel terahertz wave polarization modulator that can be used in multiple fields such as high-speed wireless communication, the Chinese Academy of Sciences' ...
When the Harvard-Smithsonian Center for Astrophysics announced a press conference for a “Major Discovery” (capital letters in the original e-mail) involving an unspecified experiment, rumors began to ...

Wave-like domain walls drive polarization switching in sliding ferroelectrics, study finds
Sliding ferroelectrics are a type of two-dimensional (2D) material realized by stacking nonpolar monolayers (atom-thick layers that lack an electric dipole). When these individual layers are stacked, ...
The following is excerpted from Chapter 3: Radio Basics for UHF RFID from the Book, The RF in RFID: Passive UHF RFID in Practice by Daniel M. Dobkin. Order a copy of The RF in RFID: Passive UHF RFID ...
Terahertz (THz) waves, which are located between microwaves and infrared light in the electromagnetic spectrum, can pass through many materials without causing damage, making them useful for security ...
