This engineering study describes using antenna-coupled microwave radiation to enhance laser-induced breakdown spectroscopy (LIBS) emission from a Gd2O3 sample at reduced pressure. The authors report substantially increased plasma emission intensity, higher-temperature plasma, and longer emission lifetime when…

This study measured dielectric properties of beef Semitendinosus across 27, 915, and 1800 MHz and temperatures from -5 to 130 °C using an open-ended coaxial probe. The results indicate that frequency, temperature, and muscle fiber orientation influence dielectric constant, dielectric loss, and calculated penetration…
