PECS (International Workshop on Photonic and Electromagnetic Crystal Structures) will be held at Sendai, Japan, in March 2000. It is an international workshop that follows up the line of WECS (Workshop on Electromagnetic Crystal Structures) at Laguna Beach, USA, in January 1999. The recent progress and increasing interests on photonic and electromagnetic crystals are far exceeding the expectation of anyone. The expanding research area covers physics, optoelectronics, chemistry, biology, etc. The aim of this workshop is to provide a timely forum for presenting the latest novel and innovative works on new physics, technologies and device applications.


The technical program will consist of single regular session with oral and poster presentations. The oral presentations include a plenary talk and invited talks on the recent topical and significant progress. The official language will be English, which will be used for all printed materials, presentations and discussions. Original contributed papers reporting new research and development results are solicited.

The workshop covers any topics concerning photonic/electromagnetic crystals and related structures, namely, periodic structures that control waves. The scope is as follows:
