Laser Action in Pi-Conjugated Polymer Microcavities
ISBN: 9783639131833 / Angielski / Miękka / 156 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Polymers in general are a class of materials known to be excellent insulators. However -conjugated polymers are different in that they possess semiconductor characteristic properties. They actually can be transformed into excellent conductors with conductivities close to those of good metals by doping. In addition to electrical conductivity, -conjugated polymers also show luminescence upon electrical or optical excitation. Furthermore stimulated emission is another crucial feature of such materials that provides the possibility of attaining laser action. The present work concentrates on a...

Development of four novel UWB antennas assisted by FDTD method
ISBN: 9783639158724 / Angielski / Miękka / 184 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. In this work, the finite different time domain (FDTD) method was selected for the design and optimization of UWB antennas in many different application areas. They include ground penetrating radar (GPR), anechoic chamber feed antenna, near field probe antenna and tapered chamber feed. All these antennas require UWB operation, dual linear polarization, and broad beamwidth. For each application area, they have their own detail operation requirements. With the help of the FDTD code and through understanding, the antennas are deeply studied and analyzed for the final design. This process saves...

Laser/Microstructure Interaction and Ultrafast Heat Transfer
ISBN: 9783639163933 / Angielski / Miękka / 224 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The industrial demand for smaller structures
required for the manufacture of quantum devices and high density recording media have resulted in the need for fabrication technology at the nanometer scale. It is shown in this text that laser/microstructure interaction can break the diffraction limit, creating nanoscale surface modifications in both localized and parallel fashions. Two fundamental problems required for predictive optical nanolithography are addressed here: the electrodynamic response of laser energy in the vicinity of micro/nanostructures, and the resulting energy...
