Dual-PEEC Modeling of a Two-Port TEM Cell for VHF Applications [PDF]
, 2011 Two-port TEM cells with rectangular cross section are commonly used to produce plane electromagnetic waves with high electric field. The non-uniform structure makes the use of numerical methods extremely useful in the design phase in order to achieve a ...

Seasonal Temperature Extremes in the North Eurasian Regions Depending on ENSO Phase Transitions
Atmosphere, 2022 Seasonal anomalies of surface air temperature were analyzed for the North Eurasian regions in mid-latitudes using long-term data from the end of the 19th century with an assessment of El Niño Southern Oscillation (ENSO) effects.

Tuning the Mott transition in a Bose-Einstein condensate by multi-photon absorption [PDF]
, 2006 We study the time-dependent dynamics of a Bose-Einstein condensate trapped in an optical lattice. Modeling the system as a Bose-Hubbard model, we show how applying a periodic driving field can induce coherent destruction of tunneling.

High-performance planar light-emitting diode
, 2002 Planar light-emitting diodes (LEDs) fabricated within a single high-mobility quantum well are demonstrated. Our approach leads to a dramatic reduction of radiative lifetime and junction area with respect to conventional vertical LEDs, promising very high-
