===README/NOTES for the matlab files that create the mask for the Big Display===

mask_draft1.m makes 3 sets of 1000 transducers of different frequencies.

the calculation done for the spacing between the fingers of the transducers is v=f*lambda, where f is the frequency and v ~= 4000. This is done in DmakeDevice_1Tgrating()

most of the changes in the code are located in DXFTRYgrating.m

three sets of 1000 transducers (500 on each side of the set) takes about 1hr. to complete

==FILE INFO==

Dmakerect.m files: Dmakerect.m makes the long rectangle used to connect the transducers with the bonding pad (along with the rects made with Dmakerect4 or Dmakerect5). It is also used for the mirror strips. Dmakerect2.m makes a grounding pad that is close to the mirror strips Dmakerect3.m makes the wirebonding pads Dmakerect4.m makes a thin rectangle that connects the rect made by Dmakerect.m to the wirebonding pad furthest away from the transducer. Dmakerect5 makes a thin rectangle that connects the rect made by Dmakerect.m to the wirebonding pad closest to transducer.

Dmakebox.m simply makes a box 10 units by 10 units.

DXF_poly makes prints the shape you have made with one of the Dmakerect files

maketransducerwithoutpads.m and maketransarray.m are similar to DXFTRYgrating and DmakeDevice_1Tgrating, respectively, in some ways are far as code goes if you want to see another example of transducers. However, what they make are completely different.

DXF_line.m prints a line to the file from two given (x,y) coordinates.
