  • A Four-Element 'Clover' Transceiver Array For 3 Tesla Cardiac MRI

    The design of radio frequency (RF) coils is of paramount importance to the quality and safety of Magnetic Resonance Imaging (MRI). Being the signal generator and detector of MRI, RF coils are required to generate a uniform excitation in the target during transmission and high signal-to-noise ratio (SNR) during reception. In the meantime, RF coils must not cause subject overheating in in-vivo human studies. This requires that RF energy deposited inside the human body and coupled to receivers should be minimized.

  • Ultra-Low Power Wakeup Radios And The Internet Of Things
    Ultra-Low Power Wakeup Radios And The Internet Of Things

    The growth of the Internet of Things (IoT) is expected to accelerate in the coming years, propelled by the lower cost and increasing connectivity of the network. Many of the communication devices for the IoT will have power constraints, due to their small size and the requirement to operate off small batteries for long periods of time. This paper will examine some of the requirements of such low power communication systems, the need for low power wakeup radios with example applications, and a comparison of candidate technology.

  • Combined 3D Electromagnetic And Spin Response Simulation Of MRI Systems

    This white paper addresses the benefits of using 3D electromagnetic software for simulation to accurately represent the behavior of magnetic fields used in MRIs.

  • A Multiphysics Approach To Magnetron And Microwave Oven Design

    The magnetrons used in microwave ovens operate on the same frequency band as Wi-Fi equipment, and the radiation they release can interfere with the operation of wireless networks. This paper presents a multiphysics simulation of a magnetron using CST STUDIO SUITE®, with the aim of testing the electrical, magnetic, thermal and mechanical characteristics of a low-interference magnetron design. The simulation results are then compared to measurements made experimentally, and the two sets of results are shown to be in good agreement.
