At ferromagnetic-resonance frequencies, in small ferrite samples so-called magnetic-dipolar-mode oscillations can be excited. The near fields in vacuum, originated from a ferrite disk with these oscillations, are unidirectional rotating fields. When a thin metal wire is placed above such disk, unique torsion electric currents are induced. We analyze analytically these torsion effects. The torsion...
Recently, using near-field scanning microwave microscopy (NSMM) is gaining popularity in many areas. However as of today in areas of medical diagnostics and nondestructive test it fails to meet the expectations. The conventional NSMM are measuring only by displacement of resonance frequency or by decrease of Q-factor which depends from dielectric and conductivity properties of materials. Because in...
This paper proposes a randomized variable probability pattern in under-sampling acquisition for medical image matching which is a method that can perform the quantitative analysis of tissue parameters. For high-speed estimation of tissue parameters, random under-sampling with less than the Nyquist rate in k-space is required. This study presents an accurate parameter mapping method for under-sampled...
In a normally magnetized thin-film ferrite disk with magnetic-dipolar modes, one can observe magneto-electric oscillations. Such magnetoelectric properties of an electrically small sample can be considered as very attractive phenomena in microwaves. In this paper we discuss the question on novel microwave device applications based on ferrite magnetoelectric particles.
