Generalized magnetoionic formulae for the propagation of radio waves in the F region of the ionosphere As the effective collision frequency of the electron in the F region is much less than the probing frequency (usually, HF), an approximation to the ... KVV Ramana,DNM Rao,BJ Rao - 《Rad...
The analysis of biomedical signals for clinical studies and therapeutic applications can benefit from embedded devices that can process these signals locally and in real-time. An example is the analysis of intracranial EEG (iEEG) from epilepsy patients for the detection of High Frequency Oscillations...
Measuring the spectral properties of an optical frequency comb is among the most fundamental tasks of precision metrology. In contrast to general single-parameter measurement schemes, we demonstrate here single shot multi-parameter estimation of an optical frequency comb at and beyond the standard quantu...

of probing many interfaces, and with advancement of both theory and instrumentation it has provided valuable information to more challenging systems.7–9Many techniques are capable of surface characterization, such as scanning electron microscopy (SEM), tunneling electron microscopy (TEM), and x-ray ...
Parametric Decay of a Circularly Polarized Electromagnetic Wave in an Electron-Positron Magnetized Plasma We study the parametric decays of an electromagnetic wave propagating along an external magnetic field in an electron-positron plasma. We include weakly re... L.,GomberoffV.,Muñoz - 《Astrophys...
High precision radio-frequency-size-effect measurements of the temperature dependent scattering rate have been performed in Cu and Ag down to 0.5K. The data can only be described by introducing a term αT2 from electroń-electron scattering with α\cong2·106 [s-1 K-2] in fair agreement wit...
In this paper, we show a fundamental limit on the operating frequency of twisted pairs beyond which twisted pairs start to radiate and behave like an antenna. To validate our theoretical derivations through measurements, we designed a microstrip balun to excite the differential mode on the twisted...
Notably, the accumulation of the 2D ammonium salt on the surface causes the anomalous Fermi energy level at the front side20. This will lead to spontaneous electron extraction behavior. For this band structure, during dark–light transitions, photons enter from the indium tin oxide (ITO)/PEDOT:...
