Thermoplastic Nanocomposite Optical Materials

Near-Field Optical Characterization of Nanocomposite Materials

*We present a near-field optical technique *-hich makes use of the strongly enhanced optical field at a laser-illuminated metal tip. The enhanced field is used to locally excite the sample under investigation by multiphoton absorption. An optical scan image w-ith spatial resolutions dow-n to 20 nm is established by detecting the emitted fluorescence. The principle of the method is described and...

Thermoplastic Materials Applications in Radiation Therapy.

This is an example of the use of thermoplastic materials in a high-tech medicine field, oncology radiation therapy, in order to produce the rigid masks for positioning and immobilization of the patient during simulation of the treatment procedure, the imaging verification of position and administration of the indicated radiation dose. Implementation of modern techniques of radiation therapy is ...

Wave Propagation in Nanocomposite Materials

Electromagnetic wave propagation is first analyzed in a composite material mde of chiral nano-inclusions embedded in a dielectric, with the help of Maxwell-Garnett formula for permittivity and permeability and its reciprocal for chirality. Then, this composite material appears as an homo-geneous isotropic chiral medium which may be described by the Post constitutive relations. We analyze the pr...
