coulld you suggest me few excellent books on the above topics,very descriptive books.

Or any good sites,any sugesstion on the frequency propagation in tunnel.

Shareware software that calculate the optimum frequency for best propagation in tunnel. Or attenuation at a specific frequency in a specific tunnel dimension.

Thanks
