Microwave Absorption in Rare-Earth Metals

Journal of Applied Physics, 1965
Microwave absorption phenomena have been investigated in single crystals of the rare-earth metals Tb, Dy, Ho, and Er, at frequencies of 9.44 and 35.3 Gc/sec over the temperature range 10° to 290°K. Microwave absorption occurs at the critical field transitions for the antiferromagnetic phase.

Absorption of microwaves in the microwave oven

The Physics Teacher, 2001
A microwave oven is used to demonstrate that, in comparison to liquid water, both ice and liquid nitrogen are almost completely transparent to microwaves. The difference in transparency is also simply explained.

Critical Slowing-Down in Microwave Absorptive Bistability

Topical Meeting on Optical Bistability, 1982
In this experiment one utilizes a microwave confocal open resonator in the transmission configuration, having a Q factor of 5 105. The resonator is filled with ammonia gas at the pressure of 1 mTorr. A klystron oscillator, frequency stabilized on the 3-3 ammonia inversion line, feeds the resonator which is tuned at the same frequency.

A wearable microwave absorption cloth

Journal of Materials Chemistry C, 2017
A wearable microwave absorption cloth was assembled from a novel multi-scale graphene-supported carbon/nonwoven composite absorber coupled with a reflection plane. The as-fabricated cloth that fulfills the representative wearable characteristics presents qualified microwave absorption performance, promising outstanding platform for the development of ...

Microwave absorption in magnetic bilayers

Journal of Magnetism and Magnetic Materials, 2001
The simulation of ferromagnetic resonance spectra was performed on the exchange coupled bilayer thin films within the classical electromagnetic model at the perpendicular configuration. The inteface exchange interaction and the surface magnetic anisotropy were assumed to be bilinear and uniaxial, respectively.

Microwave absorption in polar liquids

1948 Conference on Electrical Insulation, 1948
The dielectric constants and loss factors of twenty-seven liquid organic halides have been measured at 1.27 and 3.2.2 cm. wavelength and used, together with certain additional measurements at 10 cm. and with measurements of viscosities, densities and refractive indices, to examine the accuracy of the equations for dielectric behavior and the relations ...

Modulated microwave absorption in superconductors

Solid State Communications, 1992
Modulated microwave absorption in conventional superconductors at low magnetic field is discussed. The microwave losses in the mixed state of superconductors are described in terms of viscous motion of vortices depinned by the critical state magnetization current.

Microwave Absorption Characteristics of Tire

2015
The recycling of waste tires has been a big environmental problem. About 280 million waste tires are produced annually in the United States and more than 2 billion tires are stockpiled, which cause fire hazards and health issues. Tire rubbers are insoluble elastic high polymer materials.

Paramagnetic Resonance Absorption of Microwaves

The Journal of Chemical Physics, 1951
Paramagnetic resonance absorption in approximately a hundred salts in the powder form, containing atoms of the iron and rare earth groups and organic as well as inorganic radicals, has been investigated. The frequencies employed range from 9000 to 50,000 Mc/sec.

Anomalous microwave absorption in superconductors

Physica, 1971
Abstract A calculation of the surface impedance of superconductors was given by Mattis et al. where electron scattering at the surface was considered to be random or specular. The present treatment is equivalent with the previous ones as far as the linear transport theory is concerned, but makes use of a different type of boundary condition by ...
