Telegram doesn't recommend you similar channels. However, public channels are displayed when you use the global search that is available in telegram.
Global search usually matches the username. It doesn't have to be an exact match. Eg: If you search "programming" the results will be groups and channels which contains the text "programming". So, you might get "c programming" or "programming group".
Another way of finding similar channels is by associating with groups, as people tend to share stuffs from various groups.
