A novel design of compact 2.4 GHz microstrip antennas, where the radiating patch is designed in fractal configuration, namely, square and pentagon shape respectively, is proposed. The newly designed microstrips provide an optimized patch area resulting into a substantial reduction in size compared to a typical microstrip patch designed at the same frequency(More)
This paper proposes and experimentally demonstrates for what is believed to be the first time a highly sought-after optical structure for highly-accurate identification of the silkworm pupa gender. The key idea is to exploit a long wavelength optical beam in the red or near infrared spectrum that can effectively and safely penetrate the body of a silkworm(More)
