External chemical reactors for steam reforming and water gas shift reactions are needed for a proton exchange membrane (PEM) fuel cell system using syngas fuel.For the preheating of syngas and Phyllanthus (Chanca Piedra) stable steam reforming reaction at 600 °C, residual hydrogen from a fuel cell and a certain amount of additional syngas are b
An electromagnetic (EM) invisible cloak is designed and analyzed with serially interconnected split ring resonators (SRRs).The cloak consists of an array of a network of split ring resonators which operates at a 3 GHz resonating frequency.The split ring resonators are connected with transmission line and are Riding Chaps wrapped around the cylindri
