We present in this paper an active waveguide effect observed in porous anodic alumina (PA), which can be applied in optical sensors. The spectral position, shape, and polarization effect of the narrow waveguide modes is described. An analytical test with a commercial pesticide was performed.

    Microwave undulators have two features that make them attractive to use in free-electron lasers, when compared with conventional static magnetic undulators. One is that the beam aperture is larger than the period, and thus the undulator period is smaller than that achievable with static systems....

    Composites of alumina (Al2O3) ceramic and single-wall carbon nanotubes (SWNTs) have been tested in uniaxial compression at 1300 and 1350 °C (Ar atmosphere), and they have been found to be about two orders of magnitude more creep-resistant compared to a pure alumina of about the same grain...
