Researchers create metasurface that enables multichannel #terahertz transmission @opticalsociety https://phys.org/news/2023-03-metasurface-enables-multichannel-terahertz-transmission.html

"The devices operate on the basis of electrostatic control of collective electromagnetic interactions at deep subwavelength scales, as an alternative to controlling the flow of electrons in traditional devices, such as diodes & transistors..enables a new class of electronic devices with cutoff frequency figure-of-merit well beyond ten terahertz, record high conductance values, extremely high breakdown voltages & picosecond switching speeds"

Here's an interesting new #terahertz science result: #cyclotron emission from #Landau levels in HgTe quantum wells. Typically, emission from Landau levels is hard to observe with parabolic bands, because of the equally spaced ladder of states. Emission always loses to absorption.

But in a 2D #topological system, bands are non-parabolic and the Auger mechanism is suppressed. This portends future developments in Landau lasing, covering 0.5-3 THz. Very exciting!

Well, I was going to toot about some cool new results in #terahertz science but oh gosh look at the time.

So instead here's a photo of our dog. Ain't she cute.

Woof @ Wednesday.

Magnet-Sandwich als Mittler zwischen zwei Welten: Ein Forschungsteam unter Leitung @HZDR hat eine Methode zur effizienten Kopplung von #Terahertz-Wellen mit deutlich kurzwelligeren #Spinwellen entwickelt. Die Experimente klären im Zusammenspiel mit theoretischen Modellen die grundlegenden Mechanismen dieses bisher für unmöglich gehaltenen Prozesses auf. Die Ergebnisse sind ein wichtiger Schritt für die Entwicklung neuartiger Technologien zur Datenverarbeitung.

I'm really impressed with this work!

@oldmapgallery I enjoy pointing out that the #terahertz portion of the #spectrum is always centrally located in these diagrams. Hey terahertz folks! We're at the center of it all!

Things that annoyed me the most about #terahertz science and technology in 2022:

1)...

2)...
.
.
.
n) the rise of the "terahertz wand" which somebody is apparently SELLING as a therapeutic device. It is one of the most common things that comes up when I search twitter for "terahertz".

I know, I know, snake oil salesmen have been around since forever, but this is a little close to home, intellectually speaking.

Caveat emptor.

n+1)...

Well, I can't decide on the best #terahertz stories of 2022, but I can point to the result that I most wish I had thought of doing, but somebody else got to it first. It's this one, published back in March:
https://rdcu.be/c2w3X
This describes terahertz #circular_dichroism measurements on polycrystalline samples of various different amino acids. The data indicate the presence of #chiral terahertz #phonons in some cases. Very difficult experiments, but very impressive results!

I've been trying to come up with a list of the top #terahertz stories of 2022 (my personal opinion).

The trouble is, there are too many cool things to include.

Maybe I'll get there before 2023.
