Artificial spin ice, a class of lithographically created arrays of interacting ferromagnetic nanometre-scale islands have been intensively investigated during the last few decades due to the competing interactions [1, 2]. The degenerate magnetization ground state resulting from frustration in spin ice structures is one of the subjects that have attracted a lot of attention. It may result in potential...
A novel broadband substrate integrated rectangular waveguide (SIRW) power divider is presented. Based on the equivalent-circuit method, broadband impedance matching about the current probe circuit has been achieved. A four-way SIRW power divider operating at X-band has been designed, fabricated and measured. Good agreement between simulated and measured results is found. The measured 15 dB return...
A new broadband in-phase power divider based on multilayer technology is presented. A simple design procedure is developed for the proposed multilayer power divider. An S-band four-way multilayer power divider was designed and measured. The simulated results are compared with the measured data, and good agreement is reported. The measured 15 dB return loss bandwidth is demonstrated to be about 72%,...
