Summary:The probability‐density function for waves propagating in a straight perfect electrical conductor (PEC) rough‐wall tunnel is deduced from mathematical models of random electromagnetic fields. The field propagating in caves or tunnels is a complex‐valued Gaussian random process, analyzed using the central‐limit theorem. The probability‐density function for single‐modal‐field amplitude in such a structure is Ricean. Since both the expected value and the standard deviation of this field depend only upon the radial position, the probability‐density function, which indicates the power distribution, is a radially dependent function. © 2005 Wiley Periodicals, Inc.
