Abstract-Microwave oven generates a harmful electromagnetic wave at 2.45 GHz of 1000 Watts. The generated microwave is confined within the cavity of the oven for efficient heating and secured operation. To prevent microwave leakage through the front glass door, a special construction of Faraday Cage is involved. In this paper, Faraday Cage is replaced with Transparent Frequency Selective Surface Front Door, which provides better visibility and avoids microwave energy to escape from the oven. Two works are proposed in this paper. The first one is band pass response which has been achieved for 10 GHz by printing array of Greek cross aperture (FSS) on the front glass door, and the second work is band stop response which has been achieved for 2.45 GHz frequency by printing the array of circular ring patch (FSS) on the front glass door. Design of two different FSS arrays and the simulation results were discussed.

“…Accordingly, numerous wireless signals exist in indoor spaces, causing problems such as unhealthy influences harmful to the human body or the deterioration of communication performance owing to interference between signals. A reconfigurable frequency selective surface (FSS) was proposed as a method to adjust the propagation environment to serve the users' objective by actively blocking or transmitting particular signals in indoor spaces, as well as solving the abovementioned problems [1,2,3]. However, the proposed FSS is being manufactured in PCB form by using chemical methods of etching copper on substrates.…”

In this study, a paper-based reconfigurable frequency selective surface (FSS) that can be applied as wallpaper inside buildings to control the indoor spectrum was designed using the ink-jet printing method. The designed paper-based FSS uses a PIN diode to block 5 GHz band signals in the OFF condition and to transmit the signals in the ON condition, offering frequency characteristics stable to polarization and incident angles. To verify the operation of the designed FSS, the FSS was printed on a 0.2 mm thick paper using the ink-jet printing method by attaching a PIN diode using a conductive adhesive to manufacture the FSS with a switching function. It was confirmed that the measured frequency transmission characteristics according to the switching operation corresponded to the calculated results, and stability was exhibited for polarization and incident angles.

“…Over past years, FSSs have been extensively used in a variety of applications such as designing stealth radomes for aircrafts, dichroic reflector antennas, EM shielding for EMC and RCS reduction by EM absorbers to name a few [2]. A passive FSS has some limits because it offers no flexibility once fabricated, whereas an Active FSS (AFSS) allows the potentiality of control by changing the behavior of the surface [3][4][5][6][7][8][9][10][11][12][13][14]. As far as we know, the reconfigurable AFSSs can be divided into two main categories.…”

Abstract-A dual-polarized active frequency selective surface (AFSS) with switch function at LTE-D band is proposed in this paper. Double coupled metallic meandered structures on a one-layer substrate loaded PIN diodes are designed carefully to realize the band-pass characteristic at 2.6 GHz when PINs are OFF and the rejection characteristic when PINs are ON. The proposed model requires no additional biasing lines, and the amount of PINs is acceptable and affordable, which contribute to the simplicity and practicality of this AFSS in real applications. A simple equivalent circuit model (ECM) is given to better understand the design. Through full-wave simulation results, the polarization characteristics under TE and TM are almost the same, and the angle-stability stays well till 45 • . For necessary verification, one finite FSS prototype was fabricated, which was changed to one switchable AFSS by welding PINs and external feeder lines. The measured results of transmission coefficient are obtained by free space test method in the microwave anechoic chamber and agree well with the simulated ones.
