Embodiment 1

[0050] This embodiment provides a method for implementing an L-shaped shaped field source assisted by metal scatterers. First, according to step 1 of the technical solution, construct an L-shaped basic shaped field source. The specific method is to discretize the L-shaped geometry, such as image 3 As shown, the spacing D of its discrete sampling points is required to be slightly less than half a wavelength (60mm), so D=59mm in the present invention; secondly, arrange the scatterers according to the steps of the technical solution and related theories, and realize the scatterers based on metal scatterers. Shaped field source construction:

[0051] (1) Make sure that the position of the metal scatterer is around the shaped field source, such as figure 1 As shown, the distance between the metal scatterer and the shaped field source dw=0.2×D;

[0052] (2) Determine the distance between the metal scatterers themselves. The distance between most adjacent metal scatterers is the s...

Embodiment 2

[0064] This embodiment provides an implementation method of a T-shaped shaped field source assisted by metal scatterers, which is the same as the implementation method of an L-shaped shaped field source assisted by metal scatterers. First, construct a T-shaped basic shaped field source, such as Figure 7 As shown, it is composed of 13 spatially discrete array elements, and the array element spacing is also D (59mm); secondly, the structure is based on the shaped field source assisted by metal scatterers, such as figure 2 As shown, at the position dw=0.2×D away from the basic shaped field source, the metal scatterers are arranged according to the steps of the technical solution of the present invention; the distance between most of the scatterers is D the same as the distance between the shaped field source array, and the special position is the corner According to the principle of straight line intersection, the intersection point is the spatial position of the scatterer, dw3...

Abstract

The invention provides a method for constructing a shaping field source based on metal scattering body assisting, and belongs to the technical field of electromagnetic wave space propagation and control. The method is different from the method which uses the simple space discrete array for building the shaping field source. The novel method for constructing the shaping field source by adding a simple metal scattering body around the space discrete array or outside the shaping field area is provided on the basis of the electromagnetic scattering wave random phase cancelling principle in a composite medium space, and is used for sharpening an edge field of the shaping field and reducing the problem of excessive and overhigh side lobes outside the area. The method has the advantages that the geometric boundary of the shaping field can be sharpened, the problem of the side lobes outside the shaping field area can be effectively solved, the operation and implementing are simple and convenient, the complicated and time-wasted space field calculation and number optimizing are not needed, and the constructing difficulty of the high-quality shaping field source is greatly simplified.

Description

technical field [0001] The invention belongs to the field of space propagation and control of electromagnetic waves, and in particular relates to a method for optimizing the structure of a shaped field source in electromagnetic field shaping. Background technique [0002] The application of electromagnetic waves in the fields of communication, medical treatment, and industry has made people pay attention to and study the propagation control technology of electromagnetic waves. Antennas and their arrays, metamaterials, and circuit devices are all ways to control wave propagation, mainly through various This method controls the propagation direction of the wave, that is, the control of the pattern. With the continuous expansion of the application range of electromagnetic waves, especially in the fields of biology, medicine, chemistry, industry, etc., the research on various control problems of "wave field" has begun to attract the attention of scholars. The regeneration of th...
