A Dual Resonant Microstrip Antenna for UHF RFID in the Cold Chain Using Corrugated Fiberboard as a Substrate
… unfeasible. In this thesis we propose a novel dual-resonant planar UHF RFID microstrip antenna designed to be both insensitive to the content/environmental conditions of the corrugated fiberboard box and economically feasible. We provide simulated performances and experimental validations to …

Computer simulations for constant-frequency resonant power processors
Simulations of two types of constant-frequency resonant power converters using SPICE-2/I-G SPICE are performed. The first one is a parallel resonant converter (PRC) using a controlled output rectifier. The PRC is operated at a constant frequency and its output voltage is regulated by controlling …

The Gopher Antenna: A New Type of Ground Penetrating Radar Antenna
… The concept of a patch antenna with a dual resonant structure was used as a basis. To achieve this goal, a feed antenna with three resonant frequencies was used. The novel point in the design is the second resonant frequency (not the first, as is typical) of the feed that is matched to …

Development of optomechanofluidic resonators
… tapered optical fibre is employed. This hybrid dual-resonant system consisting of an OMFR shell and contained fluid can be considered a radiation-pressure driven acoustic resonator. The optical modes do not significantly interact with the contained fluid directly, therefore neither the fluid nor …

Hybrid inductive and capacitive wireless power transfer system for future transportation electrification
… gain and load-independent operation at designed resonant frequency instead of at dual resonant frequencies in the conventional model. Fourth, a novel hybrid inductive and capacitive wireless power transfer system is realized by combining both systems using a three-leg, mixed switching frequency …

Quasinormal Modes of Nearly Extremal Black Holes
… of these objects and the idea of co-modes or dual resonant states: solutions to the adjoint problem which can make identifying the frequencies easier. Finally, we shall use this framework and Gohberg-Sigal theory to prove existence results for zero-damped modes: firstly in the case of wave …

Enhancement of Inductive Power Transfer Technology: Iron-based Nanocrystalline Ribbon Cores
… contribution, a control strategy that uses the dual-resonant frequency characteristic of LCCL-compensated pads is also presented. This strategy was validated experimentally, and it can be used to increase the power transfer capability of pads under misaligned conditions. Moreover, this strategy …
