In this post we will have a look at modes for zero-dimensional systems, and how to relate eigenvalue/eigenvector analysis to more standard analyses of such systems, and how resonance comes into play in the whole thing.


Certain systems can be described as being zero-dimensional. When this...

I think the concept of ‘modes’ is often misunderstood. I certainly have been confused at times (and sometimes I still am). I think some of the confusion comes from textbooks, and blog posts, not being concise enough in their description, and also that the concepts are introduced differently in diffe...

This post is just a small one; I was playing around with acoustic topology optimization, and inspired by the Acoustic Demultiplexor, I had an idea about having two inputs, each of them assigned to each their output, without any explicit 'tubing' being possible for this 2D case. At one input a certai...

I have for the past couple of years tried to push the development of Microacoustics Optimization (especially Topology Optimization) and get more focus on its research and engineering development. Even though it is still very much an unexplored topic, there has been work done with Microacoustics and...
