As a practical demonstration of the associated capabilities, a small object was hidden from view, appearing to be empty space, using negative index metamaterials in 2006.[6] Furthermore, in the news, as early as May 2006, there was discussion about using negative index materials for military applications, at radar frequencies. For example, the beam would be directed around the electromagnetically secreted object, returned to their original trajectory

In addition, negative index metamaterials have a design flexibility that allows for control and direction of the permittivity and permeability values in 2-dimensional space, taking positive or negative values as desired.[2][22]. In this instance, two-dimensional space is referred to because the object is hidden only on the same plane as the line of sight to the hidden object
اون قرمزه یعنی چی؟ به خصوص اینکه کاربرد یا معنی as در اینجا چیه؟
With these new synthetic materials, electric displacement fields, magnetic field intensities, focus of rays, dispersion of frequencies, angles of deflection, and flow around an object by these fields, ending with return to their original angles of trajectory — all these properties can be controlled
اون قرمزه چیه؟
herefore, referring to the Snell's law, the transmitted beam and the incident beam are never on the same side of the normal. [1] Hence, upon entering a naturally occurring material from air, n > 1.[1] From the knowledge and experience in optics, developed over centuries, there are now a wide variety of lenses which range over a broad spectrum, from radio to optical
قرمزه یعنی چی؟
microstructured materials [that] can be designed with considerable magnetic activity, both diamagnetic and paramagnetic, and can, if desired, be made extremely light ... [and]... strong magnetic activity implies strongly inhomogeneous fields inside the material. In some instances, this may result in local field strengths many orders of magnitude larger than in free space. [Also], doping the composite with nonlinear material at the critical locations of field concentration gives enhanced nonlinearity, reducing power requirements
در اینجا many رو چطور ترجمه کنم؟ بدون اون میتونم ولی با اون نه؟
و سوال اخر ایا با این شیوه یعنی پرسیدن اون قسمتهایی از ترجمه که اشکال دارم ایا روزی میرسه که خودم بتونم اشکالاتم رو برطرف کنم یا اینکه باید یه فکر اساسی کنم. اخه برام جای تعجب داره که لغات رو تکی بلدم ولی نمیتونم در بعضی موارد مفهوم جمله رو بفهمم.
