In this manuscript, a microwave resonance sensor (MRS) was presented composed of interdigital structure, meander structure, chandelier‐form, and T‐shaped structure. The combination of four structures results in a good electromagnetic field strength at the sensing location. It caused increased sensitivity. Due to the high use of methanol in industry, samples have been selected from this material. The samples used are methanol and water solution and place on location sensing. For measurement was used samples with 80% methanol with a permittivity of 59%–10% methanol with a permittivity of 77. Also, tissue samples including sheep, chicken and fish have been used to measure the proposed sensor. The resonance frequency of the samples changes in the range of 2.14‐1.46 GHz. The sensitivity of the presented MRS is 2.6% and the Q‐factor is 1252.

“…The performance of different kinds of sensors varies greatly. For example, the magnetoresistive sensor is suitable for the measurement of low frequency magnetic field [18], and the refractive index sensor based on supermaterial is a hot research topic in recent years, but its performance in terahertz frequency band is excellent [19,20]. In fact, there are many factors affecting the sensor measurement of surface current density, especially frequency response, size, and power, but the current more popular sensor technology will be the development direction of surface current density measurement.…”

The transient surface current density reflects the external coupling of the electromagnetic pulse (EMP) to the tested device. In this paper, the generation mechanism and measurement principle of conductor surface current density are introduced, and the surface current density distribution irradiated by EMP on a typical aircraft structure is simulated and analyzed. The traditional surface current density is usually measured by B-dot antenna, but its output signal is the differential of the measured signal, so additional integrators or numerical integration of the measured data are required. In this paper, a self-integrating surface current sensor based on optical fiber transmission is designed based on the shielded loop antenna with gap structure. The output signal is the real signal waveform to be measured. Compared with coaxial cables, integrated optical fiber transmission improves the anti-interference ability of long-distance transmission signals. At the same time, the design process of the sensor is introduced in detail. The bandwidth of the sensor is 300 kHz~500 MHz, the sensitivity is calibrated at 1.23 (A·m−1)/mV, and the dynamic range is ±25~1400 A·m−1 (35 dB). The surface current of a metal plate is measured in a bounded wave electromagnetic pulse simulator using a detector developed in this paper. The test results show that the developed sensor has good engineering applicability.
