1. A system for inspecting a composite structure, the system comprising:

  • a transmitter capable of transmitting microwave energy directed toward the structure;

    a receiver capable of receiving microwave energy scattered from the structure; and

    a controller connected to the receiver for analyzing the microwave energy scattered from the structure, the controller capable of determining a dielectric constant of the structure using an inverse scattering algorithm and comparing the dielectric constant of the structure to a dielectric constant of at least one sample structure, wherein the composite structure and the at least one sample structure are separate structures such that the transmitter is configured to transmit microwave energy toward the composite structure without also concurrently irradiating the at least one sample structure.
