Reading physorg.com, I came across this story about miniaturizing antennas for smaller wireless devices. Apparently, the size of the antenna often limits the size of the wireless device – so let’s make those antennas smaller. The article is about a group from the University of Michigan who achieves this by using a hemispherical substrate with a spiraling antenna taking advantage of the volume that the hemisphere provides.

As part of COMSOL’s commitment to the Multiphysics Modeling community, we offer a forum where COMSOL models and other material can be shared; the Model Exchange. I was just looking through the Model Exchange when I noticed a user from way back had posted their model of a horn antenna.

One of the things I do at COMSOL is to make some of the images we use in our marketing material. I was working on a picture of a piezoelectric microtweezer for an ad that would be used for our MEMS Module, as the one you can see below. That’s when I started wondering what these microtweezers actually do.

Alla har vi väl velat bli osynliga vid ett eller annat tillfälle. Som Dagens Nyheter och Ny Teknik nyligen rapporterade om har vi på COMSOL dragit vårt strå till stacken. Forskare använder COMSOL Multiphysics för att simulera och designa avancerade metamaterial. Redan idag finns det högeffektiva antenner och i framtiden går det kanske att skapa akustiska mantlar, båtskrov med lägre vattenmotstånd eller osynlighetsmantlar. Det lär nog dröja ett tag innan en hel människa försvinner in i mörkret bakom en osynlighetsmantel […]
