Evolution of Magnetic Ring Designs for Phase Plates

Investigation of magnetic resonances for different split-ring resonator parameters and designs

We investigate the magnetic resonance of split-ring resonators (SRR) experimentally and numerically. The dependence of the geometrical parameters on the magnetic resonance frequency of SRR is studied. We further investigate the effect of lumped capacitors integrated to the SRR on the magnetic resonance frequency for tunable SRR designs. Different resonator structures are shown to exhibit magnet...

TEM imaging and application of thin-film magnetic rings for phase plates

The maximum out-of-plane field that some thin-film cobalt rings resisted while remaining in the vortex state was found experimentally to be lower than expected from simulation, possibly due to tilt. Analysis of a Zernike phase plate shows that the observed bright outlines around large objects result from the low-spatial-frequency limit of correction imposed by the beam hole. The maximum size of...

Design of Superresolved Phase Plates

Diffraction limit is always a key point to almost all optical systems, and diffraction effect is mostly dependent on the numerical aperture of objective and wavelength of light. However, it will be ultimately limited to improve the resolution continuously by increasing the numerical aperture or reducing the wavelength. Here, it is introduced that when these two parameters are fixed, focal spot ...

Ring Diagrams and Electroweak Phase Transition in a Magnetic Field

Electroweak phase transition in a magnetic field is investigated within the one-loop and ring diagram contributions to the effective potential in the minimal Standard Model. All fundamental fermions and bosons are included with their actual values of masses and the Higgs boson mass is considered in the range 75GeV ≤ mH ≤ 115GeV . The effective potential is real at sufficiently high temperature....
