With this app you can take a floorplan of your house set the location of a WiFi router and simulate how the electromagnetic waves propagate see an example here:brbrhttp:www.gfycat.comImportantSafeBlackmambabrbrThis is based on a recent blog post 39Helmhurts39 at www.jasmcole.com which was featured on io9 Ars Technica the Daily Mail Scientific American and many other blogs.brbrThis app uses the 2D Finite Difference Time Domain method to solve Maxwell39s equation on a Cartesian grid. An example floorplan is included in the app.brbrHow to use:brbrYour floorplan needs to be a .png file with empty space marked black and materials marked with colours. Images will be converted into the correct materials on loading this may take a few seconds.brbrPixels are mapped to 1 centimetre so scale the floorplan appropriately.brbrThe simulation is limited in speed due to the mobile processor so try to keep images below approximately 500×500 pixelsbrbrTouch the image to set a router location marked by a red circle. Select the antenna parameters at the bottom.brbrSet the number of iterations to run for how often to plot the result and the upper limit on the colourmap scale.brbrChoose a field to plot the default is the outofplane electric field.brbrClick run and the simulation will begin. Click stop to pause at any time this saves the simulation progress which can be continued by clicking run again. To reset open an image again.brbrTo save the simulation output as an image click Save at any time. Images are saved to internalexternal storage and added to the end of the camera roll.brbrTo start recording a simulation click the record 39R39 button. When the simulation is stopped a GIF animation is generated.brbrUnder the bonnet:brbrAn antenna oscillates at 2.4 GHz. The edges of the image use absorbing boundary conditions as in Mur 1981 IEEE Transactions on Electromagnetic Compatibility.brbrWhere walls are defined the relevant refractive indices and loss tangents for 2.4GHz radiation are used.brbrWavelength and resolution are currently constant this may change in a future release.brbrbrDisclaimer:brbrThis app is not intended as a replacement for existing EM simulation software packages.brAs a 2D approximation including only simple walls it does not accurately model a given floorplan.brbrIt is however a bit of fun and entertaining to play with.
