In this paper, a summary of works in creating truly three-dimensional structures for high-frequency applications will be presented using an additive manufacturing method, laser-based layer-by-layer polymer stereolithography. This polymer stereolithog

This paper presents a new lumped-element absorptive bandstop filter topology. It exhibits infinite attenuation at the center frequency and no reflection regardless of the quality factor ( $Q$ -factor) of the resonators. The new topology exhibits the

In a multiple-receiver wireless power transfer (WPT) system, determining the condition for uniform power distribution at a high transfer efficiency is a challenging issue. In this paper, a selective WPT technique using magnetic resonance coupling (MR

In this paper, we show a second-order (four-resonator) absorptive bandstop filter circuit topology which gives a larger bandwidth compared to a first-order topology. Due to the absorptive characteristic, it creates a large attenuation at the center f

The prospects for and the state of the art of adaptable RF hardware are reviewed, focusing primarily on the traditional frequency planning bottleneck, the filtering stages. First, a case is made that even banded systems can be greatly impacted by a m

Reconfigurable resonator arrays offer the unique advantage of providing an adaptive order filter response by appropriately routing signals of interest through the desired resonators. However, this approach typically results in wasted resources since
