testing and verification of embedded systems.It allows you to incorporate MATLAB algorithms into models as well as export the simulation results into MATLAB for further analysis. It is basically a graphical block diagramming tool with customizable set of block libraries. Simulink, also developed by MathWorks, is a data flow graphical programming language tool for modelling, simulating and analyzing multi-domain dynamic systems. See their website,, for lots of devices like this.Simulink is a simulation and model-based design environment for dynamic and embedded systems, integrated with MATLAB.

The boundary conditions are different than our membrane problem, but the differential equation and the solution techniques are the same. Symmetry of the H about the dotted lines shown in the contour plot of the electric field implies that only one quarter of the domain needs to be considered and that the resulting geometry is our L-shaped region. The ridges increase the bandwidth of the guide at the expense of higher attenuation and lower power-handling capability. The active region is the channel with the H-shaped cross section visible at the end of the adapter. One such device is a waveguide-to-coax adapter. Simple model problems involving waves on an L-shaped region include an L-shaped membrane, or L-shaped tambourine, and a beach towel blowing in the wind, constrained by a picnic basket on one fourth of the towel.Ī more practical example involves ridged microwave waveguides. Compare these eigenfunctions with the ones from the circular sector, which has the same reentrant corner and resulting singularity.ĩ.6397 15.1973 19.7392 29.5215 31.9126 41.4745 44.9485

Here are the first nine eigenvalues and eigenfunctions, computed by a function from Numerical Computing with MATLAB, which I will discuss in a future posting. I am going to devote a series of blog posts to the L. MathWorks has adopted a modified surface plot of the first eigenfunction as the company logo. I used the L-shaped region as the primary example in my doctoral thesis fifty years ago. This singularity limits the accuracy of finite difference methods with uniform grids. Physically, a membrane stretched over such a region would rip at the corner. Mathematically, the gradient of the first eigenfunction is unbounded near the corner. Furthermore, the 270 degree nonconvex corner causes a singularity in the solution. It is the simplest geometry for which solutions to the wave equation cannot be expressed analytically numerical computation is necessary. So, an L-shaped region formed from three unit squares is interesting for at least two reasons. Once we have the eigenvalues, it is easy to compute the eigenfunctions using sines and Bessel functions. For the circular disc and sector, the eigenvalues are zeros of Bessel functions. If the units are chosen so that the wave propagation speed is equal to one, the amplitude of a wave satisfies The wave equation describes how a disturbance travels through matter.
