Abstract
In exemplary embodiments, a transmitting layer of material having a relatively high dielectric constant and high acoustic impedance, and a receiving layer of material having a relatively low dielectric constant and low acoustic impedance are superimposed such that an optimum construction is provided which simultaneously creates optimum results for the instance of transmission and reception. The two layers are interconnected by means of hybrid techniques such that they mate in a laminar manner.
