The Complementary Split Ring Resonator (CSRR) geometry is used in conjunction with a microstrip line to create a device able to measure the electric permittivity of liquids. Simulations and measurements of the S-parameters are performed to correlate the resonance frequency and the permittivity of _ve common samples in order to calibrate the device. Once calibrated, we also provide an estimate of the permittivity of a solution of silver nanoparticles. These measurements are attractive given the limited the noninvasive techniques available for nanomaterial characterization and the lack of results at the microwave range. The results estimate the relative permittivity of the silver nanoparticles  Er(Ag-NPS)=101.16 +/- 19.53.
El anillo resonador cortado complementario (CSRR) se utilizó en conjunto con una l__nea de microcinta para crear un dispositivo capaz de medir la permitividad de líquidos. La simulación y medida de los parámetros de dispersión fueron obtenidos para correlacionar la frecuencia de resonancia calibrar el dispositivo. Una vez calibrado, fue possible obtener un valor estimado de la permitividad de una solución con nanopartículas de plata. Estas medidas son interesantes dadas las limitadas técnicas no invasivas disponibles para la caracterización de nanomateriales y la falta de medidas en el rango de microondas. Los resultados estiman la permitividad de la solución de nanopartículas Er(Ag-NPS)=101.46 +/- 19.53 .
