Improved Empirical Formula Modeling Method Using Neuro-Space Mapping for Coupled Microstrip Lines
In this paper, an improved empirical formula modeling method using neuro-space mapping (Neuro-SM) for coupled microstrip lines is proposed. Empirical formulas with correction values are used for the coarse model, avoiding a slow trial-and-error process ...

Microwave Dielectric Heating of Drops in Microfluidic Devices [PDF]
We present a technique to locally and rapidly heat water drops in microfluidic devices with microwave dielectric heating. Water absorbs microwave power more efficiently than polymers, glass, and oils due to its permanent molecular dipole moment that has ...
