A Balanced-to-Unbalanced Hybrid Ring With Arbitrary Power Division Ratio
IEEE Access, 2018 This paper presents a new balanced-to-unbalanced (BTU) hybrid ring with arbitrary power division ratio. Standard S-parameters and mixed-mode S-parameters are adopted to describe the performance requirements of the BTU hybrid ring.

Inverse-Designed Broadband All-Dielectric Electromagnetic Metadevices [PDF]
Scientific Reports, 2018 AbstractThis paper presents a platform combining an inverse electromagnetic design computational method with additive manufacturing to design and fabricate all-dielectric metadevices. As opposed to conventional flat metasurface-based devices that are composed of resonant building blocks resulting in narrow band operation, the proposed design approach ...

Optimal Design of Electromagnetically Actuated MEMS Cantilevers [PDF]
Sensors, 2018 In this paper we present the numerical and experimental results of a design optimization of electromagnetic cantilevers. In particular, a cost-effective technique of evolutionary computing enabling the simultaneous minimization of multiple criteria is applied. A set of optimal solutions are subsequently fabricated and measured. The designed cantilevers

Electromagnetic design of superconducting quadrupoles [PDF]
Physical Review Special Topics - Accelerators and Beams, 2006 We study how the critical gradient depends on the coil layout in a superconducting quadrupole for particle accelerators. We show that the results relative to a simple sector coil are well representative of the coil layouts that have been used to build several quadrupoles in the past 30 years.
