In the semiconductors, when the energy excesses the band gap, electrons and holes are generated.
Similar to this, photons must overcome the photonic band gap energy to generate the color.
Then, if we know the specific color band gap, we can make that color by control the atomic structures.
Also, we can use this in ‘Information and communications technology’ by controls of total internal

2. Market Analysis
The Market size of food service industry in Korea has increased continuously, grading "A" to yeadaham
ⓐ Expansion of food service industry
According to RGM consulting, Market size of food service industry in Korea has increased three times than 1990s.
For instance, the number of restaurants increased twice than 1990's. There are about 620 thousand restaurants in
B) US Economic
Nobody can sure When U.S economic will be good. There are complicated problem in U.S economic crisis. From microeconomic to macroeconomic like fiscal policies they have a bunch of problems. Some Economist said that there are some signs which show U.S economic are getting out from the crisis. However, Sub-mortgage problem has not solved yet. Also unemployment rate is still high

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
