  • Green's functions and relative local density of states in two-dimensional lossy structured systems 
    Nicorovici Nicolae; Mcphedran Ross; Botten Lindsay; Poulton Christopher; Asatryan Ara (Taylor and Francis, 2010)
    The local density of states (LDOS) is a function of spatial position and frequency which governs the radiation properties of sources placed within structured optical systems. We show how the enhancement or suppression of ...

    Chen Parry; Mcphedran Ross; De Sterke C; Poulton Christopher; Asatryan Ara; Botten Lindsay; Steel Michael (American Physical Society, 2010)
    In lossless periodic media, the concept of group velocity is fundamental to the study of propagation dynamics. When spatially averaged, the group velocity is numerically equivalent to energy velocity, defined as the ratio ...

    The beta-phase of Au(7)Cu(5)Al(4) undergoes a reversible shape-memory phase transformation, however there has been some uncertainty regarding the crystal structure or structures of the parent phase. Here we show that, under ...
  • Hinfinity control of active vehicle suspensions with actuator time delay 
    Du Haiping; Zhang Nong (Academic Press, 2007)
