Query: Magnetic-dipolar-mode Fano resonances for microwave spectroscopy of high
  absorption matter   Study of interaction between high absorption matter and microwave radiated
energy is a subject of great importance. Especially, this concerns microwave
spectroscopic characterization of biological liquids. Use of effective testing
methods to obtain information about physical properties of different liquids on
the molecular level is one of the most important problems in biophysics.
However, the standard methods based on the microwave resonant techniques are
not sufficiently suitable for biological liquids because the resonance peak in
a resonator with high-loss liquids is so broad that the material parameters
cannot be measured correctly. Although molecular vibrations of biomolecules may
have microwave frequencies, it is not thought that such resonant coupling is
significant due to their low energy compared with thermal energy and the
strongly dampening aqueous environment. This paper presents an innovative
microwave sensing technique for different types of lossy materials, including
biological liquids. The technique is based on the combination of the microwave
perturbation method and the Fano-resonance effects observed recently in
microwave structures with embedded magnetic-dipolar quantum dots. When
frequency of the magnetic-dipolar-mode (MDM) resonance is not equal to the
cavity resonance frequency, one gets Fano transmission intensity. With tuning,
by a bias magnetic field, the MDM resonance frequency to the cavity resonance
frequency, one observes a Lorentz line shape. Use of an extremely narrow
Lorentzian peak allows exact probing the resonant frequency of a cavity loaded
by a high-lossy-material sample. For different kinds of samples, one has
different frequencies of Lorentzian peaks. This gives a picture for precise
spectroscopic characterization of high absorption matter in microwaves.
