The actual range of parameters for which Douville and James present evidence is 0.25 ≤ w / h ≤ 2.75 {\displaystyle 0.25\leq w/h\leq 2.75} and 2.5 ≤ ε r ≤ 25 {\displaystyle 2.5\leq \varepsilon _{r}\leq 25} .
Aktuálny rozsah parametrov, ktoré Douville a James predkladajú dôkazmi je 0.25 ≤ w / h ≤ 2.75 {\displaystyle 0.25\leq w/h\leq 2.75} a 2.5 ≤ ε r ≤ 25 {\displaystyle 2.5\leq \varepsilon _{r}\leq 25} .
