A phenomenological method, with a focal point group was used. The first objective of this study was to discuss the important aspects of the design and development of LP-ITS. The second was to evaluate LP-ITS on the basis of instructors and students experiences. The third was to explore the perspectives of students and instructors about the implication of LP-ITS skills in lecture hall situations. The results were discussed in terms of the evaluation of the LP-ITS and its implications for learning and teaching activities in the lecture hall.

The architecture of first model consists of arrangement of circular patches in a square array and second model is prepared with a triangular array of circular protrusions. Both the architectures consists of upper and lower layers of protrusions. The reflection phase characteristics of above two structures are studied, In multi-layer environment the effect of some parameters on the reflection phase characteristic is discussed.
