Casimir forces arise from quantum fluctuations between plates in close proximity. Casimir force computation, in principle, needs frequency responses of the plate materials from zero to infinite. However, particularly for many emerging materials, the permittivities beyond a certain frequency cutoff are not yet known experimentally. I show that the Casimir forces can be accurately calculated when the gap distance is larger than the corresponding value of the certain frequency cutoff.
