  1. 1. A comprehensive study of resistor-loaded planar dipole antennas for ground penetrating radar applications

    Författare :Disala Uduwawala; Martin Norgren; Olav Breinbjerg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ground penetrating radar; buried object detection; dipole antennas; FDTD methods; broadband properties; baluns; simulation; optimal design; lossy media; dispersive media; clutter.; Electrical engineering; Elektroteknik;

    Sammanfattning : Ground penetrating radar (GPR) systems are increasingly being used for the detection and location of buried objects within the upper regions of the earth’s surface. The antenna is the most critical component of such a system. LÄS MER

  7. 5. Microwave Measurement Systems for In-line 3D Monitoring of Pharmaceutical Processes

    Författare :Livia Cerullo; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; permittivity; moisture content; microcrystalline cellulose; Pharmaceutical processes; dispersive media; finite element method; microwave measurements;

    Sammanfattning : The monitoring and understanding of pharmaceutical processes are important in order to achieve high-quality products at a low-production cost. The presence of water, e.g. as moisture content in the solid-state pharmaceutical material, is ofparticular interest and importance. LÄS MER
