Abstract
Most of the recent research on electromagnetic absorbers at terahertz (THz) frequencies is focused on metamaterials based absorber, which provides high absorptivity of electromagnetic (em) radiations in narrow frequency band and tailoring of em response of materials. Under this work, we have also attempted the same problem with different approach, i.e., by using combination of different materials in uniform layered configuration system. Result obtained shows em absorption of 10β20 dB in the lower and higher side of measured spectrum and high absorption of 20β30 dB in central part, i.e., from 1 to 2 THz. Materials with such broadband absorptivity find numerous military and civilian applications. Β© 2011 Wiley Periodicals, Inc.

The intrinsic characteristics of LDMOS transistor amplifier can be extracted by removing the simulated characteristics of the input side and output side of test fixtures from the overall measured characteristics. In addition, impedance-matching networks are designed with these extracted S-parameters
