An Antenna on a Button

Phil Kinnane February 24, 2012

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.

Gecko lizards use dry adhesion forces to climb vertical and even backward-slanting walls. Yet, despite the strength they provide for holding their body to such walls, you can easily pluck them from their surface, and no residue is left behind. Imagine doing that with a TV.

One of the things I have noticed from the FEM vs FVM debate is that when you want to couple other physics to fluid flow, then FEM is the best method to do this with. It’s fitting then that my colleague in our Palo Alto office, John Dunec, ran a webinar this week on Multiphysics Flow Simulations with COMSOL.

I noticed a lot of activity when I posted the question concerning “FEM vs FVM” in a previous blog post, so I started looking into it a bit. A lot of people went to the COMSOL Discussion Forum thread on the matter, from the blog, which got me thinking that this must be a hot topic out there. Not Much Debate How disappointed I was when I typed ‘FEM vs FVM’ into Google and saw that there wasn’t much to […]

An interesting discussion has been going on in the COMSOL Discussion Forum. What is the difference between the Finite Element Method (FEM) and the Finite Volume Method (FVM)?

I have just read a cool article about the University of Michigan’s solar car. Back when I was a young and hopeful engineering student in Australia , the World Solar Challenge really sparked my imagination. This is the race from the top of Australia (Darwin) to the bottom (Adelaide) across the desert where the cars are powered by solar energy, which is basically captured by solar cells on the car roofs.

The release of Version 4.2a was an exciting event for us at COMSOL. I had the opportunity to see a preview of new products and the big one for me was the Particle Tracing Module. Many of our customers and colleagues in the simulation industry had been requesting this for quite some time. I must admit that I thought it was just because they wanted a different type of postprocessing feature; another way of looking at streamlines.

COMSOL Multiphysics offers direct access to mathematical models utilized in its interfaces and allows users to customize their own theoretical model within COMSOL with unparalleled ease. Here are three video tutorials on how users can add their own Partial Differential Equations (PDEs) within the COMSOL Multiphysics interface.

As most skilled COMSOL users, I am sure you know that you are not limited to just selecting what is in our drop-down lists. Say that you have invented your own measure of structural stress. You want it to be equal to the quadratic mean of the Tresca and von Mises stresses. Go to Plot Parameters to find out what these predefined stresses are called (tresca_smsld and mises_smsld if you are modeling in 3D with the Structural Mechanics Module). Now […]

BURLINGTON, MA (November 9, 2009) — More than 700 of the world’s top practitioners of multiphysics simulation recently gathered for the fifth annual COMSOL Conference in October. Complementary events were held in Boston and then Milan, Italy. The next stop for the annual world tour of this conference focused on multiphysics modeling and simulation for engineering and scientific research is Bangalore, India, November 13-14, 2009, followed by additional conferences in Shanghai, Beijing, Tokyo, and other locations.
