    In search of a new class of stable nitroxide: synthesis and reactivity of a peri-substituted N,N-bissulfonylhydroxylamine by Patel, Bhaven, Carlisle, Julie, Bottle, Steven E., Hanson, Graeme R., Kariuki, Benson M., Male, Louise, McMurtrie, John C., Spencer, Neil, Grainger, Richard S.

    Published 2011
    “…In an approach to stabilising a bissulfonylnitroxide radical, the cyclic, peri-substituted N,N-bissulfonylhydroxylamine, 2-hydroxynaphtho[1,8-de][1,3,2]dithiazine 1,1,3,3-tetraoxide (1), has been prepared by formal nitrogen insertion into the sulfur–sulfur bond of a sulfinylsulfone, naphtho[1,8-cd][1,2]dithiole 1,1,2-trioxide. The heterocyclic ring of 1 is shown to adopt a sofa conformation by X-ray crystallography, with a pseudo-axial hydroxyl group. …”

    Interaction suppression technique for high-density antenna arrays for mm-wave 5G MIMO systems by Alibakhshikenari, Mohammad, Virdee, Bal Singh, Althuwayb, Ayman Abdulhadi, Falcone, Francisco, Limiti, Ernesto

    Published 2021
    “…High isolation between adjacent radiation elements was achieved by embedding a crisscrossed decoupling structure comprising slotted microstrip-lines and locating in the ground-plane under each slot a dielectric ring. The proposed periodic array behaves as artificial magnetic conductor (AMC) surfaces as incident waves in the substrate are fully reflected with a near zero degrees reflection phase. …”
