1. A method for enhancing communications in a wireless electromagnetic communications network (WECN) having a set of nodes, comprising: forming a communications link between any subset of nodes in said WECN; modifying an intentional signal to be transmitted along said communications link by embedding at a transmitting node an invariant structure therein; converting said modified intentional signal into analog electromagnetic waves; transmitting said analog electromagnetic waves to at least one authorized and intended receiving node; detecting said analog electromagnetic waves at said receiving node; converting said analog electromagnetic waves into said modified intentional signal at said receiving node; differentiating said modified intentional signal from environmental noise through said embedded invariant structure at said authorized and intended receiving node; recovering said intentional signal by de-embedding said invariant structure; and, repeating until all of the intentional signal has been modified, sent, detected, differentiated, and recovered along said communications link.
