3D printing
3D printing or additive manufacturing (AM) refers to any of the various processes for printing a three-dimensional object. Primarily additive processes are used, in which successive layers of material are laid down under computer control. These objects can be of almost any shape or geometry, and are produced from a 3D model or other electronic data source.

A filter is widely used in overall RF system. There are many species and structures in filter. A filter seems to be simple, but there are many considerations to design filter. In this paper, we design microstrip bandpass filter which has bandwidth of 500 MHz and center frequency of 2.5 GHz. Alumina is used as substrate, and chromium is used as conductor. Final results are achieved as follows. Ins

1. PDP TV란
- PDP TV(Plasma Display panel TV)는 기존 브라운관 TV와 달리 얇은 유리 기판을 스크린으로 한 TV를 말한다. PDP TV는 Plasma 원리를 이용한 것으로 기판 사이에 혼합 가스를 넣고 높은 전압을 가해 이온가스를 생기게 한 뒤 이를 방전하여 컬러 영상을 만들도록 한다. 이것은 기존 TV에 비해 두께와
