    • A system and method for sensing the wave impedance of a material using an RF power source with a sensor structure comprised of a metamaterial radiative filter (MRF). The wave impedance is specified or monitored by processing a differential RF signal level with an impedance calculator. The differential RF signal level is obtained from a reference source signal and a response signal. RF field-coupling of the RF source with the material effects the response signal level. In embodiments, the spectrometer is physically configured for noninvasive and invasive measurements. In embodiments, the material is sensed when shielded by RF-opaque media. In embodiments, wherein the MRF has a fixed response characteristic, the dielectric constant may be obtained with a sensing structure comprised of two transponders and a single RF frequency. In embodiments wherein the MRF has a fixed response characteristic, both the dielectric constant and the loss tangent may be obtained using three transponders and a single RF frequency. In embodiments wherein the MRF is tuned with programmed control, both the dielectric constant and the loss tangent may be obtained using two transponders and a single RF frequency.

      The broken line showing of structural features is included for the purpose of illustrating non-claimed subject matter and forms no part of the claimed design.
      The sensor device is comprised of a hollow tube having an electromagnetic coupler at a second end. The other end of the sensor, we refer to as the first end, is fitted with a pointed tip to facilitate partial insertion into a material of interest such as agricultural product, processed food, and bulk chemical material. In some applications the electronic sensor provides a means to sense an electromagnetic property including dielectric permittivity of media including grains, forage, peanuts, and soils. The figures depict the ornamental design based on a material such as a PVC plastic pipe cylinder having an attached pointed tip. The pointed tip enables insertion of the electronic sensor into the material of interest.
      The intended use of the article, wherein the ornamental design of the present invention is embodied, is to provide a sensor for monitoring the electromagnetic properties of a media.

The resonant structures are interconnected in series and are arranged, relative to one another, so as to achieve a received electrical signal with an increased voltage, when the antenna is exposed to an incident electromagnetic signal. This occurs for a majority of all possible incident electromagnetic signals and, therefore, an RFID receiver based on such an antenna provides, in a majority of cases, an improved performance.
