On the Physical Basis of Ultra-High-Frequency Electromagnetic Wave Gyroscopes Based on the Sagnac Effect

Background and Objectives: In the present paper the physical backgrounds of three types of microwave gyroscopes are presented. Materials and Methods: Using the relativistic approach the relations for output characteristics are derived to determine the main parameters and properties of the microwave gyro devices: voltage tuned magnetron (mitron) and microwave gyros based on the resonant cavity, and for microwave gyro with coil.

Why the Refractive Index Couldn't Be Negative

It had been shown that for left-handed metamaterials and generally for negative refraction media the refraction index could not be introduced uniformly and could not be considered as real, especially as negative. This index for above referred media is not expedient.
