Sitka spruce (Picea sitchensis (Bong.) Carr) is the most common commercial plantation species in Britain and a breeding programme based on traditional lines has been in operation since the early 1960s. Rotation lengths of 40-years have led breeders to adopt a process of indirect selection at younger ages based on traits well correlated with final selection,(More)
Full-wave analysis of metamaterial based microwave circuit is performed using two different FDTD formulations for dispersive medium. Both Mobius-transform technique and hybrid Mobius-ADE algorithm are employed to model media characterized by negative permittivity (Drude Model) and negative permeability (Lorenz Model) over a certain frequency range. The(More)
In this paper, non-dispersive FDTD formulation by means of implicit ADI-FDTD method is utilized to simulate electromagnetic wave propagation in meta material of DNG origin that has both negative permittivity and permeability. The problem formulation is achieved by means of auxiliary differential equation method (ADE) to simplify the dispersive Lorentzian(More)
In this paper metamaterial based dual band rectangular microstrip patch antenna for mobile GSM and Wi-Max application is presented. The antenna structure consists of quarter wave microstrip line fed rectangular radiating element and 2D array of Moore Split Ring Resonators (MSRRs) based magneto dielectric material placed right under the patch. Proposed(More)
Surface water bodies like lakes, ponds, and streams anchorage the survival of aquatic life flora and fauna and maintain ecological balance. Due to urbanization population explosion, and industrialization, the water sources are getting polluted, present paper is an attempt to evaluate the adsorption of heavy metals like cadmium (Cd), chromium (Cr), zinc(More)
