“…By proper selection of the dimensions and periodicity of the structure the EM response of the structure can be controlled to either transmit or suppress certain signals to propagate through it 1 , 4 . This feature of EBG structures make them attractive in applications requiring EM shielding, e.g., medical equipment 5 – 14 .…”

Presented here is a reactively loaded microstrip transmission line that exhibit an ultra-wide bandgap. The reactive loading is periodically distributed along the transmission line, which is electromagnetically coupled. The reactive load consists of a circular shaped patch which is converted to a metamaterial structure by embedded on it two concentric slit-rings. The patch is connected to the ground plane with a via-hole. The resulting structure exhibits electromagnetic bandgap (EBG) properties. The size and gap between the slit-rings dictate the magnitude of the reactive loading. The structure was first theoretically modelled to gain insight of the characterizing parameters. The equivalent circuit was verified using a full-wave 3D electromagnetic (EM) solver. The measured results show the proposed EBG structure has a highly sharp 3-dB skirt and a very wide bandgap, which is substantially larger than any EBG structure reported to date. The bandgap rejection of the single EBG unit-cell is better than − 30 dB, and the five element EBG unit-cell is better than − 90 dB. The innovation can be used in various applications such as biomedical applications that are requiring sharp roll-off rates and high stopband rejection thus enabling efficient use of the EM spectrum. This can reduce guard band and thereby increase the channel capacity of wireless systems.

“…Devices with higher EMI have more potential to trigger performance degradation [10]. Previous studies reported the robust electromagnetic energy emitted by wireless devices has been contributing to electromagnetic pollution [11] and is responsible for most vital medical device malfunctions [12].…”

<span lang="EN-US">This paper investigates the effect of two different heating power control systems of infant incubators on their conducted emissions. Two infant incubators which respectively employ zero-crossing control mode and phase angle control mode are observed. The research was conducted by measuring conducted electromagnetic interference (EMI) from each infant incubator's power input. Measurements are conducted both during full power condition, while the incubator's compartment temperature is far away from the temperature setpoint, and during power chopping condition, while the compartment temperature reaches the steady-state set point. Method and limit of the measurement refer to CISPR 11. It is found that conducted emission higher than the standard CISPR 11 limit occurs during power chopping on phase angle control mode. This results from the sharp rise time of voltage delivered to the heater, around 220 ns for each chopping cycle.</span>
