    Notes:
    The liquid-helium distribution system for the FSU superconducting linear accelerator has been installed and a preliminary evaluation of the system performance has been made. A heat leak of about 30 W was anticipated for the entire system. With two of the five cryostats in place, we estimate an overhead heat leak for the piping system of about 37 W.

    Notes:
    We demonstrate, by both microwave experiments and numerical simulation, that a two-dimensional lattice of metal cylinders can form a complete photonic band-gap (PBG) structure. The band structure exhibits a single broad PBG extending from zero frequency to a threshold frequency, above which all modes may propagate in some direction. A single cylinder removed from the lattice produces a defect mode localized about the defect site, with an energy density attenuation rate of 30 dB per lattice constant. The frequency dependence of the transmission through a finite thickness of this structure is also calculated in good agreement with the measurements. We suggest that the defect mode resonant cavity when formed by appropriate low loss metals may be advantageous for use in PBG high energy accelerator structures that we are evaluating.

    We present numerical simulations and microwave measurements on a loop-wire structure that acts as an effective medium exhibiting a well-defined bulk plasma frequency in the microwave regime, with an effective negative dielectric function below this plasma frequency. The dependence of this plasmonic response on the self-inductance of the constituent wire elements is made explicit. A finite structure, approximately spherical, composed of this inductive medium is studied, and reveals subwavelength surface plasmon resonances below the bulk plasma frequency. © 1999 American Institute of Physics.

    Notes:
    We present experimental data, numerical simulations, and analytical transfer-matrix calculations for a two-dimensionally isotropic, left-handed metamaterial (LHM) at X-band microwave frequencies. A LHM is one that has a frequency band with simultaneously negative cursive-epsiloneff(ω) and μeff(ω), thereby having real values of index of refraction and wave vectors, and exhibiting extended wave propagation over that band. Our physical demonstration of a two-dimensional isotropic LHM will now permit experiments to verify some of the explicit predictions of reversed electromagnetic-wave properties including negative index of refraction as analyzed by Veselago [Usp. Fiz. Nauk 92, 517 (1964), Sov. Phys. Usp. 10, 509 (1968)]. © 2001 American Institute of Physics.

    Notes:
    Recently, an electromagnetic metamaterial was fabricated and demonstrated to exhibit a "left-handed" (LH) propagation band at microwave frequencies. A LH metamaterial is one characterized by material constants—the permeability and permittivity—which are simultaneously negative, a situation never observed in naturally occurring materials or composites. While the presence of the propagation band was shown to be an inherent demonstration of left handedness, actual numerical values for the material constants were not obtained. In the present work, using appropriate averages to define the macroscopic fields, we extract quantitative values for the effective permeability and permittivity from finite-difference simulations using three different approaches. © 2000 American Institute of Physics.

    Notes:
    Fungi identified as Sphaeropsis sapinea (or synonyms) have been reported from Larix. Lack of pathogenicity tests, confusion about the identity of isolates mentioned in previous literature, and existence of distinct populations (A and B morphotypes) of the pathogen indicated the need to evaluate the ability of S. sapinea to cause disease of larch. Elongating snoot tips of Larix decidua, Larix laricina, and known hosts of the pathogen, Pinus banksiana and Pinus resinosa, were inoculated with water-agar plugs colonized with an A or a B isolate, or sterile plugs (controls). Each of five replications included five seedlings for each treatment-species combination. After 6 weeks, no symptoms had developed on control seedlings, but two-way analyses of variance revealed significant effects of isolate morpnotype and host on both incidence and severity of disease (values of p ≤ 0.01). The A isolate killed almost all shoot tips, but the B isolate killed from no P. resinosa shoots to 56% of L. laricina shoots. The average length of shoot killed by the A isolate was also greater than that killed by the B isolate. Response to the B isolate again varied among species, with greater average lengths of shoot killed on the larches (compared with the pines). Both A and B morphotypes of 5. sapinea should be considered among the fungi encountered on L. decidua and L. laricina.

    Notes:
    A fungus identified as Botryosphaeria stevensii (anamorph Diplodia mutila) causes a canker disease that results in dieback of Juniperus species in the United States. A fungus identified as Diplodia pinea f. sp. cupressi causes a similar disease of Cupressus species in Israel and elsewhere. Cultural characteristics, pycnidia, and conidia of isolates of these two pathogens were compared. The ability of each fungus to produce cankers on Cupressus sempervirens was tested. Random amplified polymorphic DNA (RAPD) marker patterns also were analysed, using Sphaeropsis sapinea (syn. Diplodia pinea) isolates as an outgroup. Results indicate the fungus identified as D. pinea f. sp. cupressi from cypress in Israel is the same as, or at least highly similar to, the fungus identified as B. stevensii (or D. mutila) from juniper in the United States. Analysis of RAPD markers indicates relatively low similarity between these isolates and those of S. sapinea. Because these results are consistent with a previously published report describing substantial morphological and isozyme differences between isolates identified as D. pinea f. sp. cupressi and those of S. sapinea, use of the name D. pinea f. sp. cupressi should be abandoned. Inconsistencies between these isolates from juniper and cypress and published descriptions of B. stevensii and D. mutila, however, indicate the need for additional investigation into the relationship of these fungi.

    Notes:
    We present a systematic study of the effect of size and shape on the spectral response of individual silver nanoparticles. An experimental method has been developed that begins with the detection and characterization of isolated nanoparticles in the optical far field. The plasmon resonance optical spectrum of many individual nanoparticles are then correlated to their size and shape using high-resolution transmission electron microscopy. We find that specific geometrical shapes give distinct spectral responses. In addition, inducing subtle changes in the particles' morphology by heating causes a shift in the individual particle spectrum and provides a simple means of tuning the spectral response to a desired optical wavelength. Improved colloidal preparation methods could potentially lead to homogeneous populations of identical particle shapes and colors. These multicolor colloids could be used as biological labels, surface enhanced Raman scattering substrates, or near field optical microscopy sources covering the full range of wavelengths in the visible spectrum. © 2002 American Institute of Physics.
