Embodiment approach 1

[0019] A semicircular negative magnetic permeability medium occupying the lower side of the cavity is placed in the resonant cavity, wherein the negative magnetic permeability medium is filled with non-magnetic Teflon material with excellent anti-aging performance. The total thickness of this negative permeability medium is d 1 , the thickness of the common medium (air medium) filled above the negative magnetic permeability is d 2 , and d 1 with d 2 The ratio is close to d 1 / d 2 =n 2 / n 1 . Two semi-cylindrical resonant cavities are put together to form a resonator, and the through holes of the two semi-circular upper covers of the split resonator are respectively connected with input and output tuners, and the resonator tuner There is a loop feeder line inside the cylindrical resonant cavity to carry out the input and output of electromagnetic wave energy.

Description

technical field [0001] The invention relates to a resonance mechanism. Background technique [0002] The concept of new artificial electromagnetic media can be traced back to the 1960s. In a paper published by the former Soviet scientist Veselago, a medium with negative permittivity and magnetic permeability was hypothesized, and it was pointed out that there are many strange electromagnetic phenomena in this medium. Anisotropic medium is a new type of artificial electromagnetic medium with periodic structure that appeared in the 1990s. It has negative permittivity and negative magnetic permeability at the same time, resulting in the electric field, magnetic field and wave of electromagnetic waves propagating in the medium. The vector no longer obeys the right-hand rule of the conventional medium, but follows the left-hand rule, so the medium is also called an anisotropic medium. [0003] With the development of microwave technology, people pay more and more attention to s...
