Rubber Microwave Absorb Material
JRAT Rubber Sheet Absorber: is a series of absorber made of rubber filled with
magnetic material. It is resonant absorber from its absorbing principle.
Flexible and thin thickness, JRAT can achieve an optimal absorbance in a narrow
band. However the band is still broader than those non-magnetic materials. The
reflectivity at normal incidence could be up to -17 ~ -25 dB at resonant
frequency. And the relative frequency width is 24% and 35% separately for the
reflectivity of -13dB and -10dB. Little change is caused by the 30 degrees
incidence and -15dB for 45 degrees. As for 60 degrees, the vertical
polarization is about -7dB and the horizontal polarization is about -13dB.
RAT is in gray color and has good strength and
aging-proof capability. It can work -50~+ 100℃ . Another heat-resistant model, silicon rubber is available that can work in
-50~+ 180℃ .
RAT must be applied closely to the metal base.

JRA Rubber
Conical Absorber : is a kind
of broadband absorber for millimeter wave . The reflectivity at normal incidence is -17dB and -25dB separately for the material thickness in wavelength
of 0.35 and 1. For 60 Celsius off normal incidence, the reflectivity
downgrades to -10~-17dB. Black, very good strength, excellent environment
resistance and durability, RA can work outside in wretched environments with
moisture and salty fog. RA is flexible can be curved when
applied. Its power handling capability is 0.3w/cm 2 and can be
operational at -50 ~ + 100 ℃ . RA is mainly used around radar and antenna, to isolate
the remit and receive antenna, to cover the ship mast, to build small anechoic
box and to cover those reflective components in testing fields, so as to eliminate interference and unnecessary
reflection.

Top big-name charm JBL J55i portable headphones
As the world's top audio brand, JBL has a strong voice in the industry, and has a huge market share in the civilian market. It is a stadium with tens of thousands of people and a small KTV room. The speakers using JBL are its display. Whether it is one of the pronouns of professionalism. In recent years, the headset industry has developed rapidly. Like most audio brands in the headset industry, JBL also values ​​the headset market. In 2012, it launched a number of headset products. Today, it is one of the codes named JBL J55i. Wear a portable headset.
With the development of the industry, the shape homogenization of headphones has become more and more serious. Various "cottages" stand out. Later, they face various design pressures and have to find another way. After all, the word "cottage" is not a good word. The JBL J55i is designed with a “square†design. The overall shape is square and the edges are round. The metal and plastic materials are combined with the unique color to create a distinctive earphone product.
The J55i is a portable design that looks solid overall, but the weight is not heavy and does not cause stress on the wearer.
The unit design of the J55i is a highlight of this headset. It adopts the fascia fixing method, which makes the unit have a large movable space, which can adapt to more people and enhance the wearing comfort.
The JBL J55i features a thicker earmuff design, soft texture, fine skin and high wearing comfort. Since the unit is not large, the earmuff will be pressed over the ear without sultry feeling.
The head pad is also thickened and the intention is to enhance the wearing comfort.
JBL J55i steel beam exterior is also one of its design features. The general headphone steel beam will be designed inside the head beam, while the J55i will do the opposite, while achieving good durability and flexibility. Improves the overall texture of the headphones and reduces the plastic smell.
The JBL J55i steel beam graduated stretching rod enhances the firmness of the earphones and is engraved with scales for easy memory and adjustment.
Another feature of this earphone is the "rotation and folding" mode. The earphone unit completes the folding of the earphone through 180 degree rotation, and the design is novel.
The JBL J55i adopts the more popular detachable change line design in recent years. If the wire is damaged, it can be changed at any time.
The iPhone-compatible design makes it easy for Apple users to use the headset to do all the functions of a headset.
JBL J55i plug
The introduction of the JBL J55i portable headset is over. The J55i is a mid-range model of the JBL headset. It has many unique features in design, and is another option for headphones users to purchase headphones.
