text: Yo, it's crucial, gotta get 'em all
  Coupling-of-modes (COM), we stand tall
  Electrode cells, low loss SAW filter in the game
  Simulation and design, gotta know the aim
  
  New approach, fast and full extraction, let's go
  For multielectrode-type grating, we flow
  Calculating field distribution, no hesitation
  Using periodic Green's function, no frustration
  
  Reflection phase determined, standing wave node's position
  Transduction coefficient, charge distribution intuition
  COM parameters for EWC SPUDT, we compute
  Simple and direct, no dispute
  
  Powerful tool for filter structure optimization
  Extracting COM parameters, no complication
  Keep it real, keep it tight
  In the rap game, we ignite!
