Allow users to simulate changes to the design to see performance impacts, such as port tuning or enclosure length.
Designing and tuning tapered, straight, or expanding transmission lines. martin j king mathcad worksheets
Martin J. King’s Mathcad worksheets are a legendary, free (donation-ware) suite of simulation tools for : transmission lines (TLs), tapered lines, mass-loaded TLs (ML-TL), horn-loaded lines, and open-baffle designs. Unlike simplified box-modeling software (e.g., WinISD), MJK solves 1D acoustic wave equations inside a line with damping material, making it the gold standard for DIY TL design.

Users can specify the density and location of "stuffing" (like polyfill or wool), which is critical for smoothing out unwanted resonances in TL designs. Why Mathcad? Why Mathcad
for the end), and the driver's offset from the start of the line.
His models moved beyond basic "lumped parameter" models (like Thiele/Small) to account for the physical dimensions and standing waves within a pipe or enclosure.
