This concept <math>\operatorname{coshc}(x) = \cosh(x) / x</math> is not notable. To begin, I checked the four sources cited in the article. The first, den Outer et al. [https://doi.org/10.1364/JOSAA.10.001209], at one point contains <math>\frac{\cosh \kappa r}{\kappa r}</math> as part of a larger equation, and that's all. The second (Körpinar [https://doi.org/10.1007/s10773-014-2118-5]), third (Sönmez [https://www.m-hikari.com/imf-password2009/37-40-2009/sonmezIMF37-40-2009.pdf]), and fourth (ten Thije Boonkkamp et al. [https://link.springer.com/article/10.1007/s10915-012-9588-5]) contain neither "coshc" nor even <math>\cosh x / x</math> for anything in place of ''x''. The article also formerly cited http://mathworld.wolfram.com/CoshcFunction.html which is currently a dead link and I can't confirm it ever existed. I found no other potential sources from a search.
