Thermal barrier coatings (TBCs) are widely used in the hot sections of gas turbine systems
as they are remarkably efficient in insulating the underlying superalloys, leading to higher …

Generalized-ray theory for time-domain electromagnetic fields in a horizontally layered
medium is developed. It can be considered as the time-domain equivalent of the intensively …

Upconversion luminescence imaging provided contrast for monitoring thermal barrier
coating (TBC) delamination progression during interrupted furnace cycling to 1163° C, with …

This essay is about superluminal motion. It is generally believed that special relativity
prohibits movements faster than the speed of light. It is explained which motion is actually …

Since the description of diffraction from the seventeenth century and the development of
optical microscopy that has followed, many approaches have been developed for breaking …

The frustrated total internal reflection theories (FTIR) from previous century are thoroughly
recalculated from the, so called, monodromy operator's point of view–a theory lunched by …

An alternative expression for the Poynting vector for monitoring electromagnetic energy flow
in confined regions of evanescent waves is presented. This expression is an intrinsic …

Dipole radiation patterns change when a fluorescent molecule comes close to the boundary
between media of different refractive indices. Near-interface molecules emit mostly into the …

A complete treatment regarding frustrated total internal reflection (FTIR) of ultrasonic waves
is presented and validated against experiments, providing a theoretical explanation for the …

In most industries, detection of substances remains important as applications differ from the
industry such as detections of materials for research, detection of toxic substances in liquids …
