The diodes model loaded active doubly periodic flat strip FSS acts as a dynamic screen, in which its surface reflectivity and transmittivity can be switched alternately and tuned through d.c. bias voltage control. The properties of FSS layer are characterized using a specially designed parallel plate waveguide (PPW) simulator that permits normal incidence excitation of the FSS under test and the responses are found between 3 to 5 GHz. It is shown that by means of d.c. bias control, the screen can be utilized in, (a) transmission mode as a dual band electromagnetic shutter, or, (b) reflection mode, as an amplitude shift keying (ASK) spatial modulator or dual band reflection canceller. In addition a hybrid de-embedding technique is employed to remove the influence the PPW simulator and reveal the true property of substrateless FSS. Typical experimental results are presented and validated against a new 3D electromagnetic (EM) modeling led de-embedding method for the composite FSS layer and PPW structure.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Characterization,Dual band,Frequency selective surfaces (FSS),Parallel plate waveguide,Substrateless[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.15676/ijeei.2009.1.1.3[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
