Microwave testing has been paid only scant attention in the literature as a method for nondestructive testing of materials, yet it offers some attractive features, especially for the testing of composite and other non-metallic materials.
Microwave techniques have been used in a large number of applications that can be classified as nondestructive testing applications, ranging from large scale remote sensing to detection of tumors in the body.
This volume describes a unified approach to microwave nondestructive testing by presenting the three essential components of testing:...

Non-Destructive Testing (NDT) techniques for the inspection of industrial structural components have to be qualified in respect to the minimum performance to be achieved. The qualification schemes relate to all aspects of the tests: procedure, equipment and personnel and the qualification of inspection should be codified in Standards. Such Standards are of two main types: those that detail the methods and procedures to be used and those that define the results which must be achieved. The European Network for Inspection Qualification (ENIQ) has as its aim the creation of a European...

Like other introductions to number theory, this one includes the usual curtsy to divisibility theory, the bow to congruence, and the little chat with quadratic reciprocity. It also includes proofs of results such as Lagrange's Four Square Theorem, the theorem behind Lucas's test for perfect numbers, the theorem that a regular n-gon is constructible just in case phi(n) is a power of 2, the fact that the circle cannot be squared, Dirichlet's theorem on primes in arithmetic progressions, the Prime Number Theorem, and Rademacher's partition theorem.
We have made the proofs...

Today's shortages of resources make the search for wear and corrosion resistant materials one of the most important tasks of the next century. Since the surface of a material is the location where any interaction occurs, it is that there the hardest requirements on the material are imposed: to be wear resistant for tools and bearings; to be corrosion resistant for turbine blades and tubes in the petrochemical industry; to be antireflecting for solar cells; to be decorative for architectural panels and to combine several of these properties in other applications. Surface engineering is the...
