Starting with inputs_pd_curved:
2+
3+
inputs_candice0 - straightened
4+
inputs_candice1 - orient wave to travel in x-direction
5+
inputs_candice2 - add shoulder
6+
inputs_candice2s - change input to soft source
7+
inputs_candice3 - turn metal to PEC layer
8+
inputs_candice3a - parameterize by frequency, not wavelength
9+
inputs_candice4 - length/time scale to match 2.5 micron dx/dy
10+
inputs_candice5 - increase dx to 10 microns, increase thickness of substrate, change width of line and air gaps
11+
inputs_candice6 - put buffer behind x=0, truncate line to 635 micron length
12+
inputs_candice7 - invert logic to subtract off superconductor, add mu difference above etch
13+
inputs_candice8 - first curve
14+
inputs_candice9 - fix PEC edges, robustify "do nothing" case to for work for flag 0, -1, -2, ...
15+
inputs_candice10 - use Ey source with alternating sign on each side of the signal line
16+
inputs_candice11 - add another curve and straight line, move soft source inside of etch region
17+
inputs_candice12 - more curves
18+
inputs_candice13 - completed meadering line
19+
inputs_candice14 - left etch behind source
20+
inputs_candice15 - finish geometry
21+
inputs_candice16 - move source to vertical line
22+
