Abstract
The utility model relates to a novel broadband multilayer absorber belonging to the technical field of microwave absorption. The novel broadband multilayer absorber comprises a high-frequency absorbing layer, a wave-transparent layer and a low-frequency absorbing layer which are connected in an overlapped manner in sequence. The utility model has good absorption effect on broad bands of 1 to 18 GHz under the conditions of smaller thickness and lighter weight.
Description
Technical field
The utility model relates to the microwave absorbing technical field, relates in particular to a kind of wideband, light weight, slim novel wideband multilayer absorber.
Background technology
Microwave-absorbing body is widely used in the various aspects in military projects such as microwave communication, electronic countermeasure, target be stealthy and field such as civilian.At present thin microwave-absorbing body many with magnetic material as absorbing medium, thin magnetic layer's material is the mode of resonance microwave absorbing material normally, this class mode of resonance microwave absorbing material mainly constitutes by add electric conductivity or magnetic consumable material (absorbing agent) in the dielectric base-material, so be divided into two kinds of magnetic loss formula and electric damage formulas again.The mode of resonance microwave absorbing material is mainly used in the narrower microwave absorbing of frequency band.In order to reach wide band wave-absorbing effect, generally be that a plurality of suction ripple layers that thickness is different are bonded together the wide band suction ripple effect that reaches at present.But because magnetic material is generally the oxide of metal and metal, a plurality of suction ripple layers are bonded together that to produce weight heavier, and the defective that thickness is bigger is not suitable for that light to weight on the wide-band usage, thickness is less a desired special occasions.
Summary of the invention
In view of above-mentioned existing in prior technology problem, the purpose of this utility model provides a kind of wideband, light weight, slim novel wideband multilayer absorber.
A kind of novel wideband multilayer absorber comprises high frequency absorption layer, wave permeation layer and low frequency absorption layer; Described high frequency absorption layer, wave permeation layer and low frequency absorption layer splice successively.So-called splice refer to high frequency absorption layer, wave permeation layer and low frequency absorption layer successively one deck cover another layer above.
Described high frequency absorption layer, wave permeation layer and low frequency absorption layer are bonding by bonding agent successively.
Described high frequency absorption layer, wave permeation layer and low frequency absorption layer splice by coating successively, and wave permeation layer is coated in above the low frequency absorption layer, and the high frequency absorption layer is coated in above the wave permeation layer.
The thickness of described low frequency absorption layer is greater than the thickness of high frequency absorption layer.
Described high frequency absorption layer comprises absorbing agent and absorption base; Described absorbing agent comprises and contains carbon and ferromagnetic material that described absorption base comprises rubber, plastics or resin material.
Described wave permeation layer comprises glass material or macromolecule electromagnetic wave transparent material.
Described glass material comprises hollow glass material.
Described macromolecule electromagnetic wave transparent material comprises polyurethane, teflon or tygon.
Described low frequency absorption layer comprises and contains carbon and ferromagnetic material.
Novel wideband multilayer absorber of the present utility model is by being provided with less high molecular foam material of density or hollow glass material between two absorption layers, thereby alleviated the weight of whole absorber effectively, and makes the very thin thickness of whole absorber.In addition, by the setting of two absorption layer different-thickness, produced the assimilation effect of good high and low frequency.
