As an avid reader of the physorg.com blog, I was pleasantly surprised to see a figure show up that could only have been made with COMSOL Multiphysics. Reading the article on thermal cloaking, I understood why.

A second user story for the next COMSOL News is also reaching completion with exciting results (read about the first one here). This is an interesting case as it wasn’t really a group of people traditionally associated with finite element that managed to perform some pretty sophisticated modeling. In fact two of them are medical doctors while the final one has his background in physics.

There is a site that is dedicated to “The Physics of Lightning Flash and Its Effects” whose goals are to “increase the knowledge of the physics of the lightning discharge and of its effects on natural and man-made systems”. It was here that I was pleasantly surprised to find a presentation by a group from EPFL, in Lausanne, Switzerland, and The University of Bologna in Italy.

These last couple of months I’ve been working together with some of our users to get the next COMSOL News together. I’ve just finished working with a great application and I thought I’d give you a sneak preview of it.

I’ve been blogging quite a bit about RF models the last few weeks. This is because, lately, we have been producing quite a number of them. A press release that was published yesterday summarizes this work: “Tutorial Package Has 20 New Models for Antenna Design, Plasmonics, and Benchmarking Electromagnetics Simulations”.

Many devices live with a dry, technical name that either basically says what the device does, or is an acronym of that dry, technical name. Very few get a nickname that sticks to become the industry standard.

Someone who saw my RFID model blog post from a few days back pointed me towards a site that talks just about RFIDs. On it, I discovered a lot of articles about using RFID in the biomedical industry. This was an application that I had never thought of before. I’d always associated RFIDs with security, tracking packages and the like.

While thinking about the blog post I published previously, about the hemisphere spiral antenna, I came across this article about RFIDs. Radio Frequency Identifications are small, inexpensive chips, which use RF to send stored information while being fixed to almost any gadget or personal effect.

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.
