Monolithic flux transformer-coupled high-Tc dc SQUID magnetometers [PDF]

open access: yes, 1995
YBa/sub 2/Cu/sub 3/O/sub 7-x/ based monolithic flux transformer-coupled high-T/sub c/ DC SQUID magnetometers operating up to 73 K have been realized. The devices are characterized by high values of the modulation voltage, up to 32 /spl mu/V at 40 K.

Multi-Objective Synthesis of Filtering Dipole Array Based on Tuning-Space Mapping [PDF]

open access: yes, 2015
In the paper, we apply tuning-space mapping to multi-objective synthesis of a filtering antenna. The antenna is going to be implemented as a planar dipole array with serial feeding.

Fully-Integrated Solid Shunt Planar Transformer for LLC Resonant Converters

open access: yesIEEE Open Journal of Power Electronics, 2022
A new topology for achieving high leakage inductance in inserted-shunt integrated magnetic planar transformers is proposed. In the proposed topology, two one-segment shunts are placed across the planar E-core air gap and between the primary and secondary

A Magnetic Integration Half-Turn Planar Transformer and its Analysis for LLC Resonant DC-DC Converters

open access: yesIEEE Access, 2019
A high frequency planar transformer with integrated leakage inductance and half-turn secondary windings is proposed for LLC isolated DC-DC converters. The primary windings are wound on both the center leg and the sides leg of an EI planar ferrite core to

Planar Fourier transforms and Diophantine approximation [PDF]

open access: yesProceedings of the American Mathematical Society, 1973
The radial behavior of its Fourier-Stieltjes transform in R 2 {R^2} is related to the modulus of continuity of a measure; in certain cases the Hausdorff dimension of an exceptional set of lines can be estimated.

Structures and characteristics of planar transformers.

open access: yesJournal of the Magnetics Society of Japan, 1988
The integration of inductors and transformers is necessary for the miniaturization of electrical devices. We have studied micro-magnetic devices such as planar inductors. A planar inductor consists of a planar coil, a magnetic film and an insulator and is fabricated on a substrate by the thin film technique.
